The normal platelet count in the adult's blood is on average 150,000 to 350,000 per microliter of blood. Values considered normal may vary depending on the method the clinical laboratory uses to perform platelet counts. This value is written on the test result provided by the laboratory as a "reference value" or VR, usually next to the result found.
Platelets are blood cells, produced in the bone marrow, and involved in the process of blood clotting (formation of a clot that stops bleeding). The platelet count test is usually asked to identify if there are any problems regarding blood clotting or diseases that may increase or decrease platelets.
The hematologist is the specialist responsible for diagnosing and treating changes in the blood.
