Blood count
MPV
LOINC 32623-1 · fL
Ranges
Reference range: 7.5–11.5 fL
What it is
MPV (mean platelet volume) is the average size of your platelets, the cell fragments that help blood clot.
Why it matters
Platelet size hints at how actively your bone marrow is producing them, adding context to the platelet count.
What high values can mean
A higher value means larger, often younger platelets, which can occur when the marrow is making them quickly.
What low values can mean
A lower value means smaller platelets and is interpreted with the platelet count and clinical picture.
How to improve it
MPV reflects marrow activity rather than lifestyle; the focus is any underlying cause, not the number itself.
Food & lifestyle
No specific food changes MPV; general healthy habits support normal blood-cell production.
Preparing for the test
Part of a complete blood count (CBC); fasting is not required.
When to talk to a doctor
An abnormal MPV is interpreted by a doctor alongside your platelet count and the rest of the CBC.
