About this test
In a peripheral smear, a thin film of your blood is stained and examined under a microscope by a pathologist. It shows the size, shape and appearance of red cells, white cells and platelets, and can reveal changes that a machine count alone may not show.
Why it is done
- To find the likely type or cause of anaemia.
- To look at unusual white cells or platelets.
- To support the diagnosis of certain blood disorders and infections.
- To confirm or explain an unusual CBC result.
Preparation
No special preparation is usually needed.
