Platelet count, a vital component of a complete blood count (CBC), measures the number of platelets in a person’s blood. Platelets are tiny blood cells crucial for clotting, preventing excessive bleeding, and wound healing. A typical platelet count ranges from 150,000 to 450,000 platelets per microliter of blood. Abnormal platelet counts can signal various medical conditions. Low platelet counts (thrombocytopenia) can lead to bleeding issues, while high counts (thrombocytosis) may indicate clotting problems. Monitoring platelet counts is essential for diagnosing and managing a range of medical and hematological conditions, ensuring proper blood clotting and overall health.
