Description
A Peripheral Blood Film is a detailed microscopic examination of your blood cells, offering insight into their shape, size and appearance that automated counters cannot provide.
About the Peripheral Blood Film
In this test, a thin layer of blood is examined under the microscope by a laboratory professional. It complements the Full Blood Count by revealing structural abnormalities in red cells, white cells and platelets — clues that help investigate the cause of anaemia, unusual infections, and certain inherited or acquired blood disorders. It is frequently requested to clarify an abnormal FBC result.
Preparation and turnaround
A routine venous blood sample is required, with no fasting needed. Because the film is reviewed manually by trained staff, results may take one to two working days, and our team will advise timing when you book. Findings are best interpreted by a doctor in the context of your other blood results.
Frequently asked questions
How is a blood film different from an FBC?
An FBC counts cells automatically, while a blood film lets a specialist visually inspect cell appearance to detect abnormalities the automated count cannot show.
Why might my doctor request this test?
It is often ordered to investigate an abnormal FBC, unexplained anaemia, suspected infection, or possible blood disorders.
Do I need to fast?
No fasting is required for a peripheral blood film.
