What do low or high platelets mean?

Platelets (PLT) help blood to clot. A result below or above the reference range can have various causes; a single value does not make a diagnosis. Your doctor will assess with a full blood count and further tests if needed. If there is a marked change or signs of bleeding, see a doctor. For a wider CBC overview, see our guide to WBC, RBC, HGB, and HCT.
