About this biomarker
Platelets help the body form clots and stop bleeding. The platelet count measures how many platelets are circulating in the blood.
Why it matters
Abnormal platelet counts can affect bleeding or clotting risk and may reflect inflammation or bone marrow problems.
What lower levels may suggest
Low platelets may be seen with immune conditions, infections, liver disease, bone marrow disorders, or medication effects.
What higher levels may suggest
High platelets may be seen with inflammation, iron deficiency, recovery after bleeding, or bone marrow disorders.
