cells/mcL

Platelets (thrombocytes) are small cell fragments essential for primary hemostasis. When blood vessel damage occurs, platelets aggregate to form a 'plug' and initiate the clotting cascade. This test measures the absolute number of platelets per microliter of blood. In a comprehensive panel (Hb, TC, DC, ESR), the platelet count is vital for assessing the body's ability to clot and identifying risks for spontaneous bleeding or excessive thrombosis.

Why Context Matters

Pseudothrombocytopenia (a false low reading) can occur if platelets clump in the EDTA collection tube. Conversely, high altitudes or extreme physical exertion can temporarily elevate counts. Interpretations must consider recent medication use like aspirin or heparin.

Lab ranges are statistical averages, not biological laws. "Normal" for a 20-year-old male isn't normal for a 60-year-old female.
