Platelet Count - The Cells That Help Blood Clot — AgeGen

A platelet count measures how many platelets — small cell fragments that help blood clot — are in your blood; it is usually part of a complete blood count and is read together with the rest of the report.

Platelets are small cell fragments that help your blood clot, and a routine blood count measures them.

The biomarker

  • Name: Platelet Count
  • Units: platelets per microliter
  • Standard range: about 150,000 to 400,000 platelets per microliter for adults (ranges vary by lab).

How to read your result

ResultHow to read it
Within rangeWithin the laboratory range printed on your own report.
Below rangeA count below your lab range needs clinical interpretation and usually a repeat test.
Above rangeA count above your lab range needs clinical interpretation and usually a repeat test.
ContextLabs use slightly different ranges and methods, so compare your value with the range printed on your own report.

What moves the needle

  • Preparation. No special preparation is needed for a platelet count; it is usually part of a complete blood count.
  • Tell the clinician. Mention every medicine and supplement you take, including aspirin or ibuprofen.
  • If flagged. Ask whether the test should be repeated and what else belongs with it.
  • Never. Do not stop or start any medicine on the strength of one value; ask your clinician first.

Why this test is worth asking for

  • It comes with the complete blood count most routine panels already include, so reading it costs nothing extra.
  • Knowing your own value against your lab's range makes a later change easier to read in context.
