The normal number of platelets in the blood is 150,000 – 400,000 platelets per microliter (mcL).
Normal value ranges may vary slightly. Some lab use different measurements or may test different specimens. Talk to your doctor about your test results.
A low platelet count is below 150,000. If you do not have enough platelets, you may bleed too much.
If your platelet count is below 50,000, your risk of bleeding is much higher. Even every day activities can cause this bleeding. You need to know how to prevent bleeding and what to do if you have bleeding.
A lower-than-normal platelet count is called thrombocytopenia. Low platelet count can be divided into three major causes:
A high platelet count is 400,000 or above
A higher-than-normal number of platelets (thrombocytosis) refers to when your body is making too many platelets
Some people with high platelet counts may be at risk of forming blood clots. Blood clots can lead to serious medical problems
