What it checks
What does a full blood count check?
A full blood count (FBC) is one of the most commonly requested blood tests. It measures the cells in your blood — red blood cells, white blood cells and platelets — and can flag patterns linked to anaemia, infection, inflammation, immune-system activity or other blood-related conditions.
Our FBC includes 15 markers. The full panel is included in our Advanced, Optimal and Cancer Marker Health Checks. It is not currently included in the Essential package.
- Haemoglobin
- Red Blood Count
- HCT (Haematocrit)
- MCV (Mean Cell Volume)
- MCH (Mean Cell Haemoglobin)
- MCHC
- RDW (Red Cell Distribution Width)
- Platelets
- MPV (Mean Platelet Volume)
- White Cell Count
- Neutrophils
- Lymphocytes
- Monocytes
- Eosinophils
- Basophils
Which packages include it
Full blood count in our packages
FBC is included in our Advanced Health Check upwards. The Essential Health Check does not currently include FBC — if FBC is important to you, the Advanced check at £155 is the most affordable option that includes it.
Advanced
£155
Includes the full 15-marker FBC, plus 12-lead ECG, urinalysis and comprehensive iron studies.
Optimal
£189
Includes the full 15-marker FBC alongside thyroid function, hs-CRP inflammation and our most comprehensive standard health check.
Men’s Cancer Marker Check
£249
Includes the full 15-marker FBC alongside PSA prostate testing and FIT bowel screening.
Women’s Cancer Marker Check
£249
Includes the full 15-marker FBC alongside CA125 testing and FIT bowel screening.
Single blood tests start from £99, with some specialist tests priced higher. For better value, many patients choose a health check package instead, which includes a broader blood panel, on-the-day checks and a clearer picture of their results.
What results may indicate
Understanding full blood count results
FBC markers are most meaningful when read together. Mildly out-of-range individual markers are common and often resolve on repeat testing.
Red blood cells and haemoglobin
Haemoglobin, red blood count, HCT, MCV, MCH, MCHC and RDW give a picture of red blood cell health. Low haemoglobin can flag patterns linked to anaemia; the supporting markers can help identify the type of anaemia (for example, iron deficiency vs B12 / folate deficiency).
White blood cells
White cell count and the differential breakdown (Neutrophils, Lymphocytes, Monocytes, Eosinophils, Basophils) can flag patterns linked to infection, inflammation, allergic responses, or other immune-system activity.
Platelets
Platelets and MPV reflect blood-clotting health. Out-of-range platelet counts can flag patterns linked to bleeding risk, inflammation or other underlying conditions.
Full blood count tests are for screening and risk awareness, not diagnosis. Mildly out-of-range results are common and often have non-serious explanations. If results suggest medical follow-up — or if you have current symptoms — please speak to your GP.
