# MPV

> MPV is measured with a standard blood draw; no fasting is needed. A typical reference range is 7.50 – 11.5 fL. TestWell offers panels that include MPV, drawn at Quest or Labcorp. An out-of-range result is a prompt to look closer, not a diagnosis.

Also known as: mpv, mean platelet volume.

## What does MPV measure?

The average size of your platelets. Larger platelets are typically younger and more active.

| age 18+ | 7.50 – 11.5 fL |

Reference intervals differ slightly between labs; the range printed on your report is the one to interpret against. Ranges are usually set so 95% of healthy people fall inside them.
