PLT (Platelet Count) is a blood test that measures the number of colorless, smallest blood cells known as 'platelets,' which are responsible for forming clots in the blood to prevent excessive blood loss. Platelets are blood components produced in the bone marrow that initiate the clotting process when a blood vessel is damaged, spreading over the surface of the vessel in the damaged area to stop bleeding.
These cells, also called 'thrombocytes,' contain numerous granules. Platelet levels are typically evaluated in laboratory reports under the abbreviation PLT as part of a complete blood count (CBC) test. It is recommended that this test be performed on an empty stomach for accurate results. After red blood cells in the venous blood sample are hemolyzed, the remaining platelets are counted. In a healthy adult, the normal platelet count typically ranges from 150,000 to 450,000 per microliter. A platelet level of more than 450,000 per microliter is termed thrombocytosis, while fewer than 150,000 platelets indicates thrombocytopenia. A drop in platelet count below 50,000 can significantly increase the risk of serious bleeding.
