  • Full Blood Count with Five Part White Cell Differential

About this test

A full blood count looks at the different components of your blood, including red blood cells, white blood cells and platelets, to give a broad picture of general health. It is commonly used to help investigate symptoms such as fatigue or feeling unwell, and can point towards issues such as anaemia, infection or inflammation.

This test has no listed comparison group, so we cannot rank it against a specific set of peers. Against the wider category of similar general wellness tests, its £135 price is around 11% above the £122 median. Better2Know also sells a nurse-kit version of the same full blood count, collected at home by a nurse, for £55, £80 less than this clinic version.

Clinical depth is low because the test is recorded as a single combined biomarker line, placing it in the bottom tenth of general wellness tests we track by marker count, even though the underlying full blood count itself covers multiple blood components. clarity and documentation scores highly thanks to a detailed description and clear collection and turnaround information. Results and follow-up is marked down because results are not doctor-reviewed as standard.

Who is it for?

This suits you if you want a broad first check on your blood health, for example if you have been feeling tired or unwell and want to rule out common causes such as anaemia or infection, and prefer a clinic or nurse-visit appointment. If cost is the main factor, Better2Know's own nurse-kit version of the same full blood count costs £80 less at £55. Speak to a GP if your results come back abnormal or your symptoms persist.

How it works

A venous blood sample is taken at a clinic or during a nurse visit and sent to the laboratory for analysis. Results are typically available within the same working day the sample reaches the lab, accessed through the online patient area; the provider does not state that a doctor reviews them as standard.
