Platelet Count Reference Range
These are the typical adult reference ranges used by major US labs. Your report will include the specific range used by the lab that processed your sample.
| Population | Range |
|---|---|
| age 18+ | 150 – 450 10^3/uL |
Reference ranges are educational. Always interpret your result with the specific range printed on your lab report and discuss anything outside the range with a clinician.
What your Platelet Count result may mean
Often reflects inflammation, recovery from blood loss, or in rare cases a marrow disorder.
May reflect viral infection, certain medications, autoimmune conditions, or alcohol use.
Educational only — not a diagnosis. Many factors can influence a single result. Discuss anything that concerns you with a healthcare provider.
