A platelet count is a blood test that measures the number of platelets, which are small cells in the blood that help with clotting. Platelets are crucial for stopping bleeding by sticking to injured blood vessels and forming clots. A normal platelet count helps doctors evaluate if a person's blood is clotting properly or if there are issues like bleeding disorders or bone marrow problems. Low or high platelet counts can be sign of various health conditions, such as anemia or infections.
