In brief
Good venepuncture is more than finding a vein. These ten steps protect the patient, the practitioner and the quality of every sample.

A blood sample may be small, but the chain of decisions around it is not. Safe phlebotomy protects three things at once: the patient, the healthcare worker and the quality of the specimen used for diagnosis.
The World Health Organization warns that poor practice can cause bruising, infection, needlestick injury, specimen contamination and dangerous clerical errors. Technical confidence therefore has to sit alongside identification, communication, infection prevention and accurate handling.
1. Confirm the request
Check that the request is complete, appropriate and linked to the correct patient. Confirm which tests are required, whether there are timing or fasting instructions and whether any tubes need special handling. If the request is unclear, resolve it before preparing to draw blood.
2. Identify the patient correctly
Use the identifiers required by your organisation and ask the patient to state their details rather than simply agreeing with information you read out. Match those details to the request and labels. Never use room, chair or bed location as an identifier.
3. Explain and obtain consent
Introduce yourself, explain why the sample is needed and describe what will happen. Check understanding and obtain consent. Ask about previous difficult blood draws, fainting, allergies, anticoagulants or other factors that may affect the procedure or aftercare.
4. Prepare the environment and equipment
Gather the correct tubes, needle system, tourniquet, skin preparation, gauze, dressing, gloves and documentation. Position the sharps container within safe reach before starting. A cluttered trolley encourages interruption and unsafe movement.
5. Perform hand hygiene and assess PPE
Clean hands at the appropriate moments and wear gloves where exposure to blood is anticipated. Gloves do not replace hand hygiene. Additional protection should be based on a risk assessment of possible splashing or exposure.
6. Position the patient safely
Support the arm and make sure the patient cannot fall if they feel faint. A patient with a history of syncope may need to lie down. Maintain privacy and keep communication calm; anxiety can affect both the patient’s experience and the practitioner’s technique.
7. Select the site and use an aseptic technique
Assess suitable veins and avoid sites that are contraindicated by local policy or the patient’s condition. Prepare the skin using the approved method and allow it to dry. Do not repalpate a cleaned site unless your technique and local protocol safely address the resulting contamination risk.
8. Draw the sample with controlled technique
Use equipment according to the manufacturer’s instructions and your training. Avoid unnecessary probing. Fill tubes correctly, follow the locally approved order of draw and mix additive tubes as directed—vigorous shaking can damage the sample.
9. Finish safely and observe the patient
Release the tourniquet at the correct point, withdraw the needle smoothly and apply pressure. Activate the device’s safety feature immediately and discard it directly into the sharps container. Never recap a used needle. Check bleeding has stopped, apply a dressing and give appropriate advice.
10. Label, document and transport
Label the sample in the patient’s presence using local policy and confirm the identifiers again. Document relevant details and place specimens in the correct transport packaging. Time, temperature, position and delay can affect some tests, so a technically successful draw can still become an unsuitable specimen if handling fails.
What competence looks like
Competence is not measured only by a successful first attempt. It includes knowing when not to proceed, when to seek help, how to respond to fainting or bleeding, what to do after a sharps injury and how to report an incident or near miss.
CFMSR’s Phlebotomy Training combines online learning with a practical day in London, simulation practice and assessment. Optional work-experience sessions are available separately for eligible learners who want to build further supervised experience.
