This test measures the number of platelets in your blood, which are essential for clot formation and wound healing. Low platelet levels (thrombocytopenia) can indicate conditions such as immune disorders, viral infections, or bone marrow diseases, leading to excessive bleeding. High platelet levels (thrombocytosis) may be associated with inflammatory diseases or blood disorders, increasing the risk of clot formation. It is commonly performed as part of a complete blood count (CBC) to assess overall blood health and diagnose clotting abnormalities, bleeding disorders, and certain types of cancer. Regular monitoring is recommended for individuals with bleeding tendencies or chronic conditions.
