A good platelet count generally falls between 150,000 and 450,000 platelets per microliter of blood. Having more than 450,000 platelets is a condition called thrombocytosis, and having less than 150,000 is known as thrombocytopenia. You can find out your platelet count through a routine blood test called a complete blood count (CBC).
The normal platelet count can vary slightly depending on factors like age and individual variations. For example, women tend to have a slightly higher average platelet count than men. It's important to consult a doctor to interpret your individual platelet count results.
