About this test

A full blood count looks at red blood cells, white blood cells and platelets in one test. According to the provider, the white blood cell count reflects the body's ability to fight infection, with moderately raised counts commonly seen in acute infection, while the red blood cell count can be low in anaemia or high in conditions such as polycythaemia. It is commonly used to help assess general blood health rather than to pinpoint a specific cause on its own.

Within its comparison group of five full blood count tests, this one is the cheapest at £54.25, below Medichecks' £59 FBC test, Bluecrest Wellness's £85 Blood Health Profile, and two larger Medichecks panels priced at £99 and £129 that cover more specialised markers such as clotting and thalassaemia screening. Its 13 markers sit close to the group's typical size. The provider notes that a postal finger-prick sample can be prone to clotting for parts of this panel, and offers a vacutainer-only (venous) collection option as an alternative, alongside a clinic visit or nurse home visit.

The listing gives a detailed explanation of what the test measures and why, which is reflected in a strong clarity score. Trust signals reflect Blue Horizon Medicals' Trustpilot score of 4.2 from 395 reviews, UKAS ISO 15189 partner labs, and a trading history back to 2009. Results are reviewed by a doctor, though this is an add-on at checkout instead of a default part of the service.

Who is it for?

This suits you if you want a general check of your red cells, white cells and platelets, for example alongside other tests, without paying for the more specialised clotting or thalassaemia panels that Medichecks offers at a higher price. Because a postal finger-prick sample can be prone to clotting for parts of this panel, if you want the most reliable result you may prefer the vacutainer or nurse home visit option over posting a finger-prick sample.

If you have symptoms that concern you, such as persistent fatigue or unexplained bruising, see your GP, who can consider a full blood count alongside your wider history.

How it works

You can provide a sample by finger-prick at home, by venous (vacutainer) draw at a clinic, or through a nurse home visit, selecting your preferred option at checkout; the provider notes that a postal finger-prick sample can be prone to clotting for parts of this panel. Once the sample reaches the lab, the full blood count is processed and the results are reviewed by a doctor, with a turnaround of one working day.
