Introduction
The Phlebotomist’s Association of Ireland was set up in 1995 by the members of
the Phlebotomy profession, to look at and address various issues of concern to the
profession and to meet the needs of phlebotomists throughout the country.
Aims
· To establish uniformity of standards within the profession.
· To formalize a recognized training programme for phlebotomists leading to
professional accreditation, and to regulate entry into the profession.
· To impose standards of behaviour and conduct on members of the association
and to provide for accreditation for those already working in the profession,
provided that they satisfy a minimum requirement criterion.
· To provide ongoing education through organized lectures, seminars and
exchange of information.
· To liaise with the HSE(with the aid of representatives of the
major Unions) in order to improve conditions, status and salary.
· To negotiate with employers for support and recognition for phlebotomy as a
profession in its own right.
Vision Statement
“The vision of Phlebotomists Association of Ireland is for phlebotomy to be recognised as a
stand-alone profession where each phlebotomist is certified and registered and is seen as a
skilled professional in his/her own right, working to national guidelines and subject to a strict
code of practice.
Through seminars and study days, we aim to provide ongoing education to enable members to
remain updated in developments within the profession.
Our members endeavour to provide the highest possible standard of phlebotomy service to our
patients and clients, helping them to overcome fear or anxiety towards the procedure. This is
achieved by ensuring that the practitioner is certified as skilled and competent to perform the
task, keeping in mind, at all times, the safety of patient, practitioner and colleagues”.
Page 5 of 29
Section 1: Code of Practice and Ethics
This Code of Practice is intended as a framework for each phlebotomist to ensure
high standards of conduct in his/her individual practice. It is intended for
practitioners working in hospitals, clinics or other environment. Any circumstances
which could have adverse consequences for the patient/practitioner or colleagues,
or which are not in accordance with safe standards of practice, should be made
known to the appropriate person or authority.
Definitions
Patient
The person presenting for a phlebotomy procedure, regardless of health or status.
Phlebotomist
The person carrying out the phlebotomy procedure, whether a dedicated
phlebotomist or a nurse/phlebotomist.
1. Professionalism And Accountability
1.1 The Phlebotomists Association of Ireland (P.A.I.) demands a high standard
of professional behaviour from its members and requires members to
conform to the National Guidelines for phlebotomy.
1.2 Although the employer is liable for the wrongs of his employees if they are
committed within the scope of their employment, the phlebotomist remains
accountable individually for his/her actions. He/she should therefore, comply
with the accepted standards of his/her profession. This standard is based on
conformity with a responsible body of opinion within the profession and is
outlined in National Guidelines. The trained and practiced phlebotomist
holds him/herself out as being proficient in a particular skill. The standard
expected is that he/she exercises the skill of a competent person exercising
that skill.
Page 6 of 29
1.3 The phlebotomist should follow the safe practice specified in the National
Guidelines, while taking account of local requirements in his/her employing
institution. Where these diverge, the phlebotomist should bring the National
Guidelines to the attention of the employer. All policies should be in writing.
1.4 The phlebotomist should be conversant and compliant with all health and
safety and infection control guidelines laid down by his/her employing
authority.
1.5 The phlebotomist should be satisfied that he/she is adequately trained and
assessed to be competent to carry out a particular procedure, before carrying
out that procedure. He/she should not carry out procedure that he/she has
not
been trained for or that he/she does not feel competent to perform.
1.6 The phlebotomist should be aware of the legal and ethical principles
applicable to his/her profession. The Phlebotomist should also be aware of
and consult local Ethics Guidelines.
1.7 The phlebotomist should be familiar with the ethical principles applicable to
the healthcare profession and behave in a professional manner at all times.
1.8 Where a phlebotomist suspects or recognizes a discrepancy or error in
instructions or orders given, he/she should bring this to the attention of the
healthcare worker ordering the test or giving the instruction.
1.9 The phlebotomist should take reasonable precautions to ensure that he/she is
not rendered incompetent by reason of health to carry out duties. Where any
condition exists to impede proper standards of procedure, he/she should not
proceed with the task. Under no circumstances can the phlebotomist
practice while under the influence of alcohol or non-prescribed or nonapproved
drugs.
1.10 The phlebotomist should not behave in a manner which members of his/her
profession would consider inappropriate, dishonourable or disgraceful.
1.11 Any form of sexual advance to a patient with whom there exists a
professional relationship will be regarded as professional misconduct.
Page 7 of 29
1.12 It is not within the scope of the phlebotomist’s practice to discuss a patient’s
condition or to inform him/her of the nature of the tests to be carried out or
the implications or results of any test that he/she may have had. However,
the phlebotomist should interact with the patient and can clarify the tests
ordered in order to help the patient to give informed consent and to promote
compliance with necessary instructions. Detailed queries should be
referred to the appropriate medical staff.
1.13 The Phlebotomist may at times be asked to partake in Research Blood
Sampling. He/she should ensure the Local Ethics Committee has given
approval and follow approved protocol.
2. Confidentiality
2.1 The phlebotomist should be aware of the ethical considerations of disclosure
of information about a patient.
2.2 The patient imparts information to the healthcare worker in good faith and
on the understanding of confidentiality.
2.3 Information regarding the patient’s history, treatment or state of health or
any privileged information disclosed to the phlebotomist in his/her
professional capacity should be regarded as confidential. Professional
judgment should be exercised in sharing this information with professional
colleagues.
2.4 The phlebotomist is closely involved in diagnostic tests and monitoring of
treatment in a variety of condition. Confidentiality is of the utmost
importance.
2.5 Relevant information should not be withheld from medical personnel
directly concerned with patient care.
2.6 The phlebotomist should be aware of the potential for computers and
electronic processing of information to breach patient privacy.
Page 8 of 29
2.7 Local Computer Usage Policy to be followed at all times.
2.8 The potential for careless handling of request forms to breach patient privacy
should be considered. Request forms should be treated as confidential
documents. All material with personal details or information on a patient
should be shredded before discarding.
3. Consent
3.1 To touch a person without consent constitutes battery or trespass to the
person. Therefore consent should be obtained prior to carrying out any
treatment or procedure.
3.2 For consent to be valid, the patient should have the capacity to give consent
(i.e. be of adult years and be of sound mind). The doctor ordering the test
should inform him/her as to the nature and purpose of the test. The
phlebotomist should then explain the procedure and gain the patient’s
consent. Consent may be expressed or implied.
Implied consent is where the patient indicates consent e.g. by holding out
an arm or pulling up a sleeve.
3.3 The patient has the right to refuse to have a procedure carried out. This
refusal should be respected and documented. The nursing/medical staff
should be informed according to the employer’s policy.
3.4 Patients under 16 years require parental consent, or consent of legal guardian
prior to venepuncture procedure.
Mental Illness:
Given that the law respects the right of a patient even with reduced mental
capacity to refuse treatment, a phlebotomist should attempt to gain the
consent of such a patient to venepuncture, either by verbal consent or
implied consent. If the patient is unable to give consent, the phlebotomist
should consult the referring doctor or nurse. Under Irish law, the next of kin
cannot consent on behalf of such a patient but can only advise the treating
doctor or nurse about what may be in the patient’s best interests. It is then up
Page 9 of 29
to the treating doctor or nurse to decide whether to prescribe venepuncture
on the basis of the patient’s best interests.
Unconscious Patient:
When a blood test has been ordered by a medical doctor for an unconscious
patient, a phlebotomist may presume that the consent has been given or that
the venepuncture has been deemed medically necessary in the patient’s best
interests. If, however, the patient has some level of consciousness, the
procedure of venepuncture should be explained to the patient.
3.5 In cases of emergency/urgent necessity, the procedure may be carried out
under general consent for treatment, in accordance with the directions of the
ordering doctor.
4. Training And Education
4.1 Should it be required, the phlebotomist should assist in mentoring, training
and continuing education by co-operating in the training of phlebotomy
students.
4.2 The phlebotomist should be aware of his/her responsibilities towards
trainees and ensure that any tasks delegated to them are appropriate to their
skill, experience and competency.
4.3 Members of the profession should keep themselves informed of current
advances that affect their profession. It is the personal responsibility of each
practitioner to maintain his/her level of competency in practice to remain
updated.
4.4 To maintain the highest standards, it is expected that each phlebotomist will
adopt this code of Practice and will adhere to the National Guidelines in
Phlebotomy.
4.5 The Certificate in Phlebotomy course is the National Training Course for the
certification of phlebotomists. This will provide for a measurable standard
and certification for all practicing phlebotomists. It is envisaged that this or
equivalent will be the minimum requirement for new phlebotomy employees
in all healthcare facilities in the future.
Page 10 of 29
4.6 The phlebotomist should be aware that there are different Phlebotomy
systems and needs to be familiar with the properties of those used locally.
5. Health and Safety
5.1 Each employer has a duty of care towards an employee. Safety in the
workplace is governed by the Safety, Health and Welfare at Work Act 2005.
The healthcare facility should have a Safety Statement available in the
workplace. Each phlebotomist should be familiar with the elements of the
Safety Statement which govern his/her practice. It is the responsibility of the
phlebotomist to read the Safety Statement. Each employing facility should
have a regularly updated policy on infection control which should be easily
available and understood by the phlebotomist. The policy should deal with
blood spillage, reporting of incidents and accidents as well as the
management of high risk patients. It should also include advice, counselling
and follow up services. Management should have a sharps policy. Hepatitis
B vaccination should be available for all at risk healthcare workers. Standard
precautions should always be observed when dealing with blood and bodily
fluids.
5.2 The phlebotomist also has responsibilities as an employee under the 1989
legislation. The phlebotomist should recognize that there is a potential risk
associated with the phlebotomy procedure. He/she should take all reasonable
precautions to protect against such risk. The phlebotomist has a duty of care
for his/her own safety at work and also that of co-workers, patients and any
persons who may be affected by his/her acts or omissions while at work.
5.3 The employee should co-operate with the employer and any other person to
such an extent as will enable his/her employer/other person to comply with
the relevant statutory provisions.
5.4 The employee should use any protective clothing or equipment provided for
use by him/her alone or in common with others in the manner intended in
order to secure his/her safety, health and welfare while at work.
5.5 The employee has an obligation to report to his/her employer or immediate
supervisor, without unreasonable delay, any defect in equipment, place of
work or system of work that might endanger safety, health or welfare, of
which he/she becomes aware.

SECTION 2: INTRODUCTION TO PHLEBOTOMY
WHAT IS PHLEBOTOMY?
Phlebotomy/venesection: Opening of a vein to drain off a quantity of blood via a wide bore
needle:
Blood analysis is an important part of the diagnosis and treatment of the patient and great care
should be taken in ensuring that a suitable specimen is obtained.
It is of the utmost importance that the patient receives a quality service.
The need for accuracy in all aspects of identification, procedure, labelling and handling cannot
be over emphasised.
Venepuncture is the most commonly performed invasive procedure for patients in hospital and
outpatient clinics. Blood collection has become one of the major diagnostic tools available.
In order to carry out blood collection safely the phlebotomist should have a basic knowledge of
the following:
(a) The relevant anatomy and physiology.
(b) The criteria for choosing the most suitable vein.
(c) Factors governing sample suitability.
(d) Use of the various blood collection devices.
(e) Procedure for labelling, handling, and transporting the sample.
(f) Complications of phlebotomy.
(g) Disposal of used equipment.
Many patients fear the prospect of undergoing phlebotomy. The phlebotomist can, with skill and
experience, minimise the discomfort and reassure the patient.
Page 12 of 29
SECTION 3: GUIDELINES FOR PHLEBOTOMY
Patients presenting for phlebotomy should have a valid request with:
· Patients name.
· Date of birth.
· Date of test.
· Location.
· Doctors name.
· Tests required.
PATIENT IDENTIFICATION
Accurate identification of the patient is essential.
Identification Requirements.
· Patients name.
· Date of birth.
· Medical Record number (M.R.N.)
· Address.
Identifying The Conscious/Coherent Patient.
In-Patient.
1. Ask patient to state name.
2. Ask patient to state Date of Birth.
3. Check MRN on request form with wrist- band.
All data is checked with the request form. Where any detail is incorrect
nursing/medical staff should correct it prior to procedure.
Page 13 of 29
Outpatient identification.
1. Ask patient to state name.
2. To state date of birth.
3. To state address.
All data is checked with the request form or G.P. letter. Where any detail is
incorrect or unspecific the phlebotomist may need to contact G.P. to verify request
prior to procedure.
Identifying the Unconscious/Incoherent Patient.
Name, D.O.B. and M.R.N. on request form should be checked with wrist- band.
Carer, relative or nursing staff should verify details.
Phlebotomy should not proceed until phlebotomist is satisfied as to correct
identity of patient.
PREPARATION
All equipment to be used in the collection of the sample should be prepared in advance.
This includes:
· Gloves/standard precaution equipment
· Alcohol hand gel.
· Disinfectant wipes.
· The request forms for the patient / computer generated labels
· Pen.
I.V. tray with
· Tourniquet
· Needles/ butterfly sets.
· Relevant collection system.
· Necessary Blood Tubes
· Alcohol Swabs
· gauze/cotton balls
· Tape/Plasters
· Signed and dated Sharps Bin, within reach.
All equipment should have expiry dates and sterility seals checked before usage.
Page 14 of 29
USE OF TOURNIQUET
· The tourniquet should be applied to the area approximately 10cm above the intended site of
venepuncture.
· It should be tight enough to restrict venous flow but not tight enough to obstruct arterial
circulation. The pulse should be palpable below the level of the tourniquet.
· The tourniquet should not be left in situ for more than one minute. Where more time is
required to find a suitable vein the tourniquet may be released and reapplied.
· When vein is selected following tourniquet application, tourniquet is released, skin cleansed
and allowed to dry, then tourniquet re-tightened to proceed with venepuncture.
· Once blood flow commences, tourniquet is released. Should flow diminish or cease before
sufficient blood is obtained, the tourniquet may be reapplied lightly.
· Tourniquet should not cause pain or discomfort to patient.
Proper use of tourniquet reduces the risk of samples being haemolysed or giving misleading
results.
Disposable Tourniquets.
These are used where transmission based precautions are required.
For example; elasticised strap with Velcro fastening or Latex strip.
A disposable glove should never be used as a tourniquet.
Page 15 of 29
CHOICE OF A SITE FOR VENEPUNCTURE
Phlebotomists are restricted to accessing the veins of the arms and dorsal hand
veins. Veins of the lower limbs and the anterior area of the wrist are not
approved sites for access by phlebotomists under PAI guidelines.
The antecubital area is the preferred site for venepuncture. Here, the median cubital, cephalic
and basilic veins lie close to the surface. This area should be examined first and then the dorsal
veins of the hand are considered.
The metacarpal veins may be suitable where no other access is available.
Venepuncture Sites To Be Avoided.
· The anterior veins in the wrist.
· Sclerosed or thrombosed veins.
· Veins close to the site of infection, bruising or Haematoma.
· Site of i.v. therapy. (May be turned off by nursing staff for 5 mins. prior to venepuncture)
· Affected side of previous mastectomy/axillary clearance, stroke, oedema fracture, burns,
amputation and fistula.
VENEPUNCTURE PROCEDURE
When the patient has been correctly identified:
· Explain the procedure.
· The patient’s arm should be supported, kept straight, in a downward position, with the
wrist extended.
· Wash Hands/alcohol gel.
· Wear gloves.
· Apply tourniquet and choose site.
· Loosen tourniquet.
· Clean Skin with alcohol swab, in a clockwise direction from within outwards.
· Assemble equipment, and let skin air dry completely….highly important in the
decontamination of the site.
· Reapply tourniquet for not more than 1 minute.
· Stretch the skin below the intended site with the free hand to anchor the vein and reduces
discomfort.
· Instruct patient to close fist lightly – no pumping.
· Expose the needle and inspect. The needle is held at an angle of 15° to 30° to the
patient’s arm with the bevel of the needle facing upwards and in line with blood flow
direction.
Page 16 of 29
· Warn the patient appropriately.
· When blood flow commences loosen tourniquet and instruct patient to open fist. If flow
is inadequate tourniquet may be lightly reapplied.
· The tubes should be filled in a downward position, using correct order of draw, until
vacuum is exhausted and blood flow ceases.
· Ensure maximum fill, to correct ratio.
· If using non pre- evacuated tube, the required amount is withdrawn by suction.
· A 21g needle is the recommended size for adult blood collection. However a 22g needle
or 23g blood collection set may also be used.
· Avoid changing hands unnecessarily while taking blood as this can displace the needle
causing pain and trauma to the patient.
· When blood has been collected, each tube should be gently mixed, by fully inverting 5 to
8 times (or in accordance of manufacturers instructions) avoiding vigorous shaking of the
tube.
· Release tourniquet fully prior to removing needle
· The last tube should be removed from the holder before the needle is withdrawn from the
vein.
· Place a gauze ball lightly over the site as the needle is withdrawn, with pressure once the
needle is fully removed.
· Immediately engage safety device.
· Pressure should be maintained until the bleeding has stopped. Patient may do this if
possible.
· Sharps are immediately disposed of in puncture resistant bin.
· Samples are labelled in the presence of the patient. Details should include:
Patient’s Name
Hospital Number
Date Of Birth
Phlebotomist’s Initials
· Place specimens in leak-proof receptacle following any special handling
requirements.
· The arm may be elevated to encourage haemostasis but bending of the arm should be
discouraged as it can lead to bruising.
· Inspect for haemostasis and apply gauze over puncture site.
· Wipe tray with disinfectant wipe. (discard if disposable)
· Remove gloves, wash hands/alcohol rub.
· Place specimens in collection area / laboratory.
· Where electronic labeling/scanning in place follow local requirements.
Page 17 of 29
DISPOSAL OF EQUIPMENT
· All sharps, both contaminated and unused should be disposed of in a YELLOWSHARP
PROOF container, properly assembled, signed and dated.
· All non-sharp, clinically contaminated materials should be disposed of in a yellow clinical
waste bin.
· General un-contaminated waste, including gloves, should be disposed of in a clear general
waste bin.
· Gloves, where visibly contaminated, should be disposed of in a clinical waste bin.
· Protective clothing, aprons, gloves etc from barrier rooms should be disposed of in clinical
waste bins, in room.
· When disposing of needles and blood collection sets, ensure the safety protection cap has
been engaged fully, before placing in a sharps container. Never separate needle from holder.
· Do not over fill sharps container.
LABELLING OF SAMPLES
General Labelling Requirements
Manual labelling .
When labelling a general sample, the following information is required:
· Patient’s surname
· Patient’s full forename
· Patient’s hospital number
· Patient’s date of birth.
· Initials of phlebotomist.
The full forename should be used. An initial for the first name is not sufficient. Blood sample
tubes should be labelled in the presence of the patient. The patient’s wristband should be checked
prior to sampling.
Page 18 of 29
Special Requirements.
· Time of sampling.
· Fasting/non-fasting.
· Posture of patient.
· Site of sampling.( Blood Culture, or I.V. infusion side)
Pre-Transfusion Sample Labelling Requirements
The labelling requirements for a pre-transfusion sample are:
· Patient’s surname (in block capitals)
· Patient’s full forename (in block capitals, an initial is not sufficient)
· Patient’s unique hospital number.
· Signature of the person taking the sample.
· Patients date of birth.
· Date and time of sampling.
· Location of patient (ward or department).
· Patients Home Address is also desirable.
Transfusion samples should be labelled by hand at patient’s bedside .
They should never be pre labelled or have addressographs applied .
Outpatient samples
The following information is required:
1. Patient’s full name.
2. Patient’s Date of Birth.
It is essential that this information is provided on the sample, otherwise the relevant laboratory
will not process the sample.
Where a minor mistake occurs, correction may be acceptable.
Correction can only be done by the phlebotomist who takes the sample .
All corrections should be initialled.
Page 19 of 29
Where electronic labelling system is in place phlebotomist follows local procedures. It is the
responsibility of the phlebotomist to ensure that all samples are correctly identified and labelled
or scanned.
The utmost care should be taken when labelling samples, as incorrectly
labelled samples may potentially have dangerous effects.
N.B. The person who draws the blood sample is the only person who is authorised to label
sample.
Sample bottles should be labelled immediately they are drawn
Bottles should not be pre-labelled under any circumstances.
Page 20 of 29
PRE ANALYTICAL VARIABLES
There are a number of factors that may render the sample unsuitable for testing or which may
interfere with accuracy of results. These are known as pre-analytical variables. They can occur at
any time from phlebotomy procedure to the testing of the sample.
MIXING OF BOTTLE CONTENTS
Immediately following blood collection, all tubes should be inverted 5 to 10 times or as per
manufacturer’s instructions, at approximately 180°. For a complete inversion, the air bubble
should move from the top to the bottom of the tube. Inverting the tubes will lead to adequate
mixing of the blood and the tube additives and give more accurate results.
ORDER OF DRAW
When taking blood, the tubes should be filled in a specific sequence in order to reduce the risk of
the additives in the bottles contaminating each other and falsifying the results of the test. The
recommended order is as follows:
1. Blood culture tubes.
2. Sodium citrate tubes – Coagulation Studies.
3. Sodium citrate tubes – E.S.R. Studies.
4. Serum tubes /dry and gel separator.
5. Heparin tubes.
6. All other anticoagulants - EDTA.
7. Fluoride/Oxalate tubes - Glucose tests.
MINIMUM FILL LEVEL
Each evacuated specimen bottle contains a pre-measured amount of vacuum. This allows the
tubes to fill a definite point, marked on the bottle with use of an arrow or dot. Suction tubes
should be filled to the mark.
If there is difficulty in obtaining the sample, it is desirable that note should be
made of it on request form. This alerts laboratory staff to check for micro clots
prior to testing.
Page 21 of 29
While it may be possible to test blood at a level below this line, the results will not be as
accurate.
For this reason, the sample may be unsuitable for testing.
Coagulation tubes which are not filled to the maximum level can not be processed as the
ratio of citrate to blood is incorrect.
Where a butterfly system is used for coagulation sampling, the tubing should be primed with a
non additive discard tube or a citrate tube. This ensures adequate fill in sample tube.
HAEMOLYSIS
Haemolysis, the process by which the red blood cells disintegrate and release their pigment,
occurs normally at the end of the life cycle of the cell. This effect is undesirable when testing the
blood, as it renders the sample unsuitable. Haemolysis usually occurs for the following reasons:
1. Using a needle with a small diameter (23g or smaller)
2. Using a small needle with a large evacuated tube.
3. Improper mixing of the tube contents and blood
4. Blood flowing too slowly into the tubes
5. Shaking or vigorous mixing of the specimen tubes.
6. Drawing from indwelling lines.
7. Drawing from site of haematoma or bruising.
8. Incorrect use of the tourniquet.
Strict adherence to protocols will reduce risk of haemolysis.
INTRAVENOUS THERAPY
If the patient requiring blood collection is receiving IV therapy in one arm, the other arm, if
possible, should be used.
If this is not possible due to medical reasons, or the patient is receiving bilateral IV therapy, then
one of the IV therapies should be stopped for 5 minutes prior to sampling. This allows natural
blood levels to recover and gives a more accurate result.Where I.V.potassium or anticoagulation
therapy is progress at access site, I.V. should be stopped for 10 minutes prior to
sampling. Nursing staff should be contacted to stop I.V. and to restart it following procedure.
Page 22 of 29
IMPROPER TOURNIQUET USE
Improper usage of the tourniquet may lead to the falsification of the results of the test. If the
tourniquet is placed too tightly on the arm, or remains in situ for too long a period of time, then
haemo-concentration or haemolysis may occur.
TECHNIQUE
If the overall technique of the phlebotomist is poor, then one or more of the previously
mentioned factors may be associated with the unsuitability of a sample.
TIMING
Where special instructions, e.g. time of day, fasting, post prandial, posture, or specified interval
following antibiotic or drug levels, are not adhered to, results may be inaccurate.
Page 23 of 29
PATIENTS IN ISOLATION
In addition to standard precautions which should be applied to all patients, transmission based
precautions are used for patients suspected or known to be colonised or infected with
transmissible micro-organisms.
TRANSMISSION BASED PRECAUTIONS
1. Source Isolation:
· Contact
· Droplet
· Airborne
The patient is colonised or infected with a communicable disease, and needs to be isolated from
other patients in order to reduce the risk of the infection spreading. e.g. Chicken Pox, Bacterial
Meningitis, MRSA, Tuberculosis etc.
2. Protective Isolation :
The patient has a weak or suppressed immune system, and is highly susceptible to infection. This
patient needs to be protected from any infection that staff or other patients may be carrying.
Information signs are used to denote appropriate precautions .
Follow instructions on sign or check with ward staff.
Phlebotomist should be familiar with Infection Control Manual.
Page 24 of 29
TRANSMISSION BASED PRECAUTIONS PROCEDURE
· Prepare equipment.
· Injection tray with sharps box, pen, appropriate tubes and blood collection set, alcohol
swabs, gauze balls, strip of tape disinfectant wipes, disposable tourniquet or and double
sheet disposable towel.. (Patient dedicated tourniquet may be left in room)
· Request form in bio-hazard bag, folded to enable details to be read.
· Wash hands with alcohol gel or soap and water.
· Don appropriate P.P.E.(Personal Protection Equipment)
· Correctly identify the patient verifying against i.d. band and request form.
· Place disposable towel sheets or plastic apron under tray.
· Perform venepuncture as per guidelines.

COMPLICATIONS OF BLOOD COLLECTION
A. Haematoma.
A haematoma is a collection of blood under the skin. This can be painful and can potentially
cause nerve damage. If a haematoma begins to form while blood is being withdrawn, needle
should be removed immediately and pressure maintained over the site.
Incident form should be completed and medical / nursing staff informed.
Causes of haematoma:
1 Small fragile vein, needle too large.
2 Excessive probing to find vein.
3 Removing needle prior to releasing tourniquet.
4 Needle going all the way through vein.
5 Needle only partially entering vein, allowing leakage.
6 Applying Pressure to gauze before the needle is removed
B. Infection
Inadequate cleansing or poor technique can lead to infection.
N.B. Follow Standard and Transmission Based Precautions .
C. Nerve damage.
Inappropriate sites or excessive probing may lead to nerve damage. Patient may complain of
severe pain. Procedure should be stopped immediately. If pain persists, incident form should be
completed and medical / nursing staff informed.
Page 26 of 29
D. Pain
While some discomfort is to be expected, the needle should be removed immediately if the
patient complains of excessive or severe pain. If pain continues, medical/nursing staff should be
informed and an incident form completed.
E. Arterial Puncture
Failure to properly identify the vein by lack of pulse and by collapse on removal of tourniquet
can result in inadvertent arterial puncture.
Where this occurs pressure should be maintained on the site for at least 5 minutes.
Nursing / medical staff should be informed and an incident form completed.
F. Syncope
Should the patient complain of weakness or suffer a syncope, the phlebotomist should
immediately withdraw and dispose of the needle. If appropriate, sips of water can be given and
patient should be reassured.
Phlebotomy chair should be fully reclined or patient lowered to supine position.
Phlebotomist stays with patient until he/she recovers.
Patient may be advised/ transferred to E.D. according to hospital protocol.
If Syncope occurs, incident form should be completed and medical/nursing staff informed.

HEALTH AND SAFETY ISSUES
SHARPS/SPLASH/INOCULATION INJURIES
A sharps/inoculation injury occurs when a clinically unclean or contaminated , or potentially
unclean or contaminated sharp e.g. needle, specimen bottle, vial etc penetrates the skin, and
exposes the recipient to risk of blood/body fluid borne diseases.
A splash injury occurs when blood/body fluid comes in contact with the skin or mucous
membranes i.e. eyes or mouth, and exposes the recipient to risk of disease.
Despite all precautions, sharps/splash and inoculation injuries do occur. Prevention of these is far
more desirable than treating one. Use of safety devices for blood collection reduces the risk of
sharps injury. Sharps Containers are effective methods of disposal of sharp clinical waste
material, as they are perforation proof. However they are not leak proof, and so, should exposed
blood products be placed in them, the risk of splash injury is increased.
The Infection Control Manual should contain the policy on treating a sharps injury. Action packs
should be available.
Phlebotomists should ensure that they are familiar with procedure for dealing with sharps injury
in their workplace.
To minimise the risk of a sharp/splash injury associated with phlebotomy procedure, the
following rules apply.
1. Patient is in a safe position with arm well supported.
2. Seek help if patient is restless or un-cooperative.
3. Ensure that vacuum bottles are disconnected from the multisampler area prior to
removing needle from vein.
4. Lightly cover venepuncture site with gauze when removing needle.
5. Engage the safety needle cover immediately upon removing the needle, and dispose into
a sharps box.
6. Never attempt to re-sheath a needle.
7. Should a sample bottle break, never attempt to pick it up. Avail of the nearest spillage kit
and use appropriately to clean the hazardous material.
8. Gloves should be worn for procedure. While this will not prevent sharp injury, the glove
has a wiping action and will reduce the amount of blood inoculated.
9. Cover all exposed cuts and abrasions with sterile waterproof dressings.
10. Should an injury occur, avoid contact of affected area with the mouth.
Page 28 of 29
All sharp injuries should be reported to the head of department. A risk management occurrence
form should be completed, and other necessary paper work also. Early treatment is vital and so
every phlebotomist should familiarise themselves with the action packs, and especially the firstaid
instructions they contain.
Spill kit should be available in all phlebotomy areas.
HANDLING OF SPECIMENS
Care should always be taken when handling blood specimens. All specimens are potentially
infectious.
Standard precautions should always be used.
1. Gloves should always be worn.
2. Exposed cuts and abrasions should be covered with suitable waterproof dressings.
3. Hands should be washed/ alcohol gel before and after each procedure.
4. All staff should be familiar with the Infection Control Manual.
External transport
Specialised containers are available to transport samples to outside laboratories. The
phlebotomist should be familiar with legislation and local arrangements.

safety standards. It specifies the manner, organisation and resources provided for that purpose.
It is the responsibility of each member of staff to read and become familiar with the safety
statement.
A copy of the Safety Statement should be available to all Phlebotomists.
ANY DEVIATION FROM THESE GUIDELINES SHOULD BE
DOCUMENTED AND KEPT ON RECORD.
