A normal platelet count in adults ranges from 150,000 to 400,000 platelets per microliter of blood. Platelets are tiny cell fragments that help your blood clot. Having too few platelets (thrombocytopenia) can lead to excessive bleeding, while having too many platelets (thrombocytosis) can increase your risk of blood clots.
The normal platelet count range may vary slightly depending on age and other factors. For example, women typically have a slightly higher platelet count than men.
Here are some additional facts about platelet counts:
- Low platelet count (thrombocytopenia): Fewer than 150,000 platelets per microliter.
- High platelet count (thrombocytosis): More than 450,000 platelets per microliter.
- Causes of low platelet count: Can be caused by a variety of conditions, including leukemia, infections, and certain medications.
- Causes of high platelet count: Can be caused by conditions like iron deficiency, inflammation, and some cancers.
If you have concerns about your platelet count, it's important to talk to your doctor.
