What does a high Mean Platelet Volume mean?

A value above the reference band means Mean Platelet Volume is outside the range typical for a healthy adult. A single reading is rarely conclusive on its own — what matters is the trend across draws and the other markers around it, which is why HealthOS reads the whole panel together rather than one number at a time.

Mean Platelet Volume: normal range and what it means

Q: How do I improve my Mean Platelet Volume?

Interpreted with the platelet count rather than alone. On its own it changes very little.

Short answer: The normal mean platelet volume range is 7.5 – 11.5 fL for adults. Labs differ a little, so also check the range printed on your report.

What it measures

The average size of your platelets. Larger platelets are younger and more active, so a high value can mean the marrow is replacing them quickly.

What moves it

Reflects how young the circulating platelets are. Rises when the marrow is replacing platelets quickly.

How to bring it into range
