The Haematology Profile is a blood test that gives a full count of your red cells, white cells and platelets, plus a marker of general inflammation. It is a good starting point if you feel unusually tired, are monitoring a known blood condition, or simply want a baseline check of your blood health. The test costs £75, plus a £50 blood-draw fee, with results in 1 day. You can walk in or book online at 117a Harley Street, seven days a week, with no GP referral needed.
This is one of the most commonly requested blood tests, ordered for symptoms such as persistent tiredness, unexplained bruising, frequent infections or simply as a general health check.
It is also used to monitor an existing blood condition, to check for infection or inflammation, or as part of routine follow-up after a diagnosis or treatment.
Many people add it to a wider health screen, since it gives useful context for almost any other symptom or profile.
Most people do not need to fast for this test and can eat and drink as normal beforehand. Follow any specific instruction from your doctor, and mention any recent illness or infection to the phlebotomist, as this can affect several of the results.
A low red cell count can point towards anaemia, while a raised white cell count often reflects infection, inflammation or, less commonly, other conditions that need further investigation. A raised ESR is a general sign that something in the body is inflamed, without saying where.
Platelet counts outside the expected range can relate to a wide range of causes, from a recent infection to how your bone marrow is working. None of these results points to a single cause on its own, so they are read alongside your symptoms and history.
If any result sits well outside the expected range, or you have symptoms alongside it, arrange to see a doctor to discuss what it might mean.
If you want these markers alongside a doctor's examination and a wider health assessment, compare the Full Body MOT health check.

It counts your red blood cells, white blood cells and platelets, giving a broad snapshot of your blood health. It is often the first test a doctor orders when investigating tiredness, infection or bruising.
It can show the pattern that suggests anaemia, such as a low red cell count, but confirming the cause usually needs further tests, such as an iron or vitamin B12 check, alongside a doctor's assessment.
Results are typically back within a day of your sample being taken. You will be able to access your laboratory report showing each result against its reference range.
