It costs £36, and once the Marylebone clinic opens on 1 October 2026 a nurse or phlebotomist takes the venous blood sample (EDTA), with the laboratory typically reporting in 1 day. Medical services are for patients aged 16 and over, self-referral with no GP referral needed, and the laboratory report is delivered to your secure portal.

Preparing for your DL3 Haematology Profile
- 1No fasting is needed and there is no preferred time of day.
- 2Drink normally beforehand; a good fluid intake makes the venous sample easier to take.
- 3Strenuous exercise in the hours before can raise the white cell count slightly, so a rest day gives a more representative result.
- 4Tell the nurse about any recent illness, as a cold can temporarily alter white cell numbers.
Sample for this test: venous blood sample (EDTA).
What DL3 Haematology Profile measures
DL3 Haematology Profile is most often requested in connection with blood cells count, bone marrow function and blood diseases, which is why it sits within the full blood count group at Wimpole Street.
A full blood count (FBC) uses an automated analyser to count and size the three cell lines in your blood: red cells and their haemoglobin, white cells broken down into five types, and platelets. Indices such as MCV and MCH describe the average red cell, while a reticulocyte count or blood film examination can be added to look at production and cell appearance. It is one of the most frequently requested tests because so many conditions leave a mark on the blood.
Who considers DL3 Haematology Profile
- People often consider an FBC if they feel persistently drained and want a broad first look for anaemia or infection.
- Frequent bruising, nosebleeds or gums that bleed easily are reasons to check platelets.
- Recurrent infections or a fever that keeps returning commonly prompt a white cell review.
- It is routinely included in health screens, pre-travel checks and monitoring of many long-term medicines.
- Anyone with a known blood condition, or a family history of one, may want an interval reading.
Understanding your DL3 Haematology Profile results
A low haemoglobin with small red cells can indicate iron deficiency, whereas large red cells may point towards B12 or folate shortage, alcohol or thyroid effects. White cell changes are read by type: neutrophils often rise with bacterial infection, lymphocytes with viral illness, eosinophils with allergy or parasites. Platelet counts outside the range, or an unexpected pattern, generally lead to a repeat sample or a blood film before any conclusion is drawn.
Many FBC variations are transient or benign; whether a flagged value needs a repeat, a further test or no action is a question for your GP or a clinician.
Related areas of testing at Wimpole Street: iron and ferritin, vitamin B12 and folate, inflammation markers, clotting and specialist haematology.
