Pre-Hair-Transplant Blood Tests: What Surgeons Ask For
Quick answer
Hair transplant surgeons in the UK typically require pre-operative bloods to identify underlying metabolic or nutritional deficiencies that could impair wound healing or compromise your recovery. A standard pre-transplant panel covers full blood count, iron studies, vitamin D, B12, thyroid function and inflammatory markers. Many clinics also request a blood-borne virus screen (HIV, hepatitis B and C).
This patient information is being clinically reviewed by our team. The factual content draws on UK guidance (NHS, NICE, British Association of Dermatologists, and other specialist society guidance where cited).
Why these markers are tested
- Healing capacity. Iron, vitamin D, B12 and thyroid function affect graft uptake and recovery speed.
- Surgical safety. A Full Blood Count screens for anaemia and platelet levels, while a Coagulation Profile ensures your blood clots normally before undergoing thousands of micro-incisions.
- Infection control. BBV screen is standard for invasive procedures.
Common features that suggest this
- Hair transplant booked or being planned
- Surgeon has asked for pre-op bloods
- Seeking to rule out hidden health roadblocks before your procedure date

Testing advice
Same-day appointment, results clinician-reviewed within 4 hours for most markers (BBV screen is 2 working days, with a 2-hour urgent option). Bring any letter from your surgeon listing specific tests required. Fast (water only) for at least 8 hours before the draw so glucose, lipid and iron-related markers reflect a clean baseline.
Common questions
Which panel should I choose?
Our foundational Pre-Transplant Screening covers Full Blood Count (for platelets), coagulation indicators (to screen for bleeding risks), and baseline nutritional, thyroid and inflammatory markers. Pre-Transplant + BBV Screen adds HIV, hepatitis B surface antigen and hepatitis C antibodies, which most surgeons require.
How early should I test?
For general health optimisation (correcting iron or vitamins), testing 8 to 12 weeks before surgery is ideal to allow time for supplementation to take effect. For standard surgical clearance (BBVs and clotting profiles), most surgeons require your blood draw to be taken within 4 to 6 weeks of your procedure date.
Can you send results directly to my surgeon?
Yes. You receive the report; you can forward it, or we can securely transfer your records directly to your surgical team's clinical inbox upon receiving your formal consent.
How does private testing compare to going through my GP?
Private testing bypasses standard primary care triage barriers, providing rapid access to a comprehensive profile without needing to meet strict NHS testing criteria first.
