About this test

A full blood count looks at the different cell types in your blood: red cells (and related measures like haemoglobin and haematocrit), white cells (including the different types such as neutrophils and lymphocytes), and platelets, along with clotting-related measures like MPV. It's commonly used as a starting point for general health screening or to look into symptoms such as fatigue, frequent infections or unexplained bruising.

At 15 markers, this sits right at the comparison-group median of 15 markers across the small number of full blood count tests we track, and at £59 it's below the £85 group median, which drives a strong value for money score. Compared with the two directly equivalent tests we track, it costs more than Blue Horizon Medicals' 13-marker version (£54.25) but less than Bluecrest Wellness's 10-marker Blood Health Profile (£85), and covers more markers than either.

If you want to go beyond a standard FBC, Medichecks also lists separate, more specialised blood tests, such as an Advanced Clotting test (19 markers, £99) and a Thalassaemia Screen (18 markers, £129), though these look at different things and aren't simply bigger versions of this test. Collection requires a venous draw at a clinic or with a home nurse rather than an at-home kit, which keeps the collection convenience score in the middle of the range, and results are back quickly, in around 2 days.

Who is it for?

This suits general health screening or a first step in investigating symptoms like ongoing tiredness, frequent infections or unexplained bruising, where a doctor might want a broad look at your red cells, white cells and platelets before deciding on next steps. On markers covered per pound, it compares well with Bluecrest Wellness's pricier, narrower Blood Health Profile.

If keeping cost to an absolute minimum matters more than the extra markers, Blue Horizon Medicals' 13-marker Full Blood Count is a little cheaper at £54.25. And if your GP or clinician is looking for something more specific, such as clotting function or thalassaemia, Medichecks' dedicated tests for those are separate, more specialised options.

How it works

This is a 15-marker blood test collected via a venous draw, either at an in-store clinic or with a home nurse visit; there is no at-home finger-prick option. Once the sample reaches the lab, results are typically back in around 2 days, and a doctor reviews and comments on every result before you see your report.

Pros & cons
