Platelet Count (PLT)
- Sample Type
- Standard
- Fasting
- No
- Unit
- x10^3/µL
Platelets (thrombocytes) are specialized cell fragments essential for hemostasis (blood clotting). When a vessel is injured, platelets adhere to the site and aggregate to form a primary plug. The platelet count is a fundamental part of the CBC, used to screen for bleeding disorders, bone marrow diseases, and to monitor the effects of chemotherapy or heparin therapy. Proper platelet numbers are required to prevent spontaneous bleeding and to ensure surgical safety.

Why Context Matters
Pseudothrombocytopenia (falsely low count) can occur if the blood sample clots in the tube or if platelets clump due to exposure to the anticoagulant EDTA. Conversely, extreme physical exertion or high altitudes can temporarily raise the count.
Lab ranges are statistical averages, not biological laws. "Normal" for a 20-year-old male isn't normal for a 60-year-old female.
