Understanding Your Full Blood Count Results

The Full Blood Count (FBC) is one of the most commonly ordered laboratory tests, and for good reason — it gives your doctor a quick snapshot of your overall health in a single blood draw.

Your report will typically show red blood cell count, haemoglobin and haematocrit, which together indicate whether you're anaemic or, less commonly, whether your blood is too concentrated.

White blood cells are your immune system's front line. An elevated count often points to infection or inflammation, while a low count can suggest anything from a viral illness to a bone marrow issue that needs further review.

Platelets are responsible for clotting. Numbers outside the normal range can affect how your body responds to cuts, bruises or surgery, and are worth discussing with your doctor rather than interpreting alone.

As always, a lab report is a conversation starter with your physician, not a diagnosis on its own — reference ranges vary slightly by age, sex and even altitude, which is why our reports always include the lab's specific range alongside your result.
