platelet count

Platelet count measures the number of platelets in your blood, which are tiny cell fragments that help your blood clot and stop bleeding. A normal range is typically between 150,000 and 450,000 platelets per microliter of blood. If the count is too low, there's a higher risk of bleeding from cuts or injuries; if it's too high, there may be an increased risk of abnormal clotting, which can lead to conditions like blood clots. Your healthcare provider may order this test to evaluate bleeding or clotting problems, monitor certain diseases, or assess the impact of treatments.
