Introduction
This guide provides a structured approach to the interpretation of a full blood count (a.k.a. FBC, complete blood count, CBC) which you should be able to apply in most circumstances.
What tests are included in a FBC?
The full blood count gives insight into the cellular components of blood including white blood cells, red blood cells, and platelets providing numerical values relating to these cells (e.g. amount of them, size, contents). These results provide vital clues to the presence of underlying pathology.
Reference ranges
We have included key reference ranges below to assist you when interpreting a full blood count.
Red cell tests
Red cell tests can quantify the amount of haemoglobin/red cells present in a sample:
White cell tests
A high white cell is known as leukocytosis and can be caused by a wide range of pathological processes. Important factors in determining the cause of leukocytosis include the rate of the white cell count rise and which type of white cell (s) are raised.
Platelet tests
Platelets (a.k.a. thrombocytes) are disc-shaped cell fragments that react to blood vessel injury by clumping to initiate the formation of a blood clot.
