Platelet volume share Plateletcrit (PCT)
The share of your blood taken up by platelets.
Also printed asPCT
What it measures
The share of your blood volume made up of platelets - the platelet equivalent of packed cell volume.
Adds little beyond the platelet count itself, and is read only when that count is abnormal.
Why it matters for how long you stay well
It adds little beyond the platelet count itself, so follow the count and treat this as arithmetic beside it.
How it shows up in daily life
You will not feel it. It moves with the platelet count and their average size together.
High and low readings
When it reads high
Tracks a high platelet count.
When it reads low
Tracks a low platelet count.
What moves it
Daily life
- everything that moves your platelet count
Read it with
Markers that move this one, or that this one moves. One number read alone can mislead.

Platelets pushes it up
Plateletcrit is the space your platelets take up in the blood. So it follows the platelet count, and adds very little of its own.
Common questions
What does Plateletcrit measure?
The share of your blood volume made up of platelets - the platelet equivalent of packed cell volume. Adds little beyond the platelet count itself, and is read only when that count is abnormal.
What does a high Platelet volume share result usually mean?
Tracks a high platelet count.
What does a low Platelet volume share result usually mean?
Tracks a low platelet count.
What is the usual reference range for Platelet volume share?
A broad adult reference band is 0.19–0.39 %. Labs differ, so read your result against the band printed on your own report.
Educational only, not a diagnosis. A single number means little without your history and the rest of your panel, so discuss your own results with your physician.

A general health marker with limited direct ageing data.
Worth knowing
It is the platelet count multiplied by their average size, so it is arithmetic rather than a separate measurement.
