<h3>What are platelets?</h3>
Platelets are pieces of very large cells in the bone marrow called megakaryocytes. They aid in the formation of blood clots that help wounds heal and to slow or stop bleeding. It can be problematic to have platelets that are too many, too few, or aren't functioning properly.
Platelets' main job is to stop and prevent bleeding. The body sends signals to platelets that direct them to the affected location when a blood artery is damaged. Adults typically have between 150,000 and 450,000 platelets per microliter of blood, which is considered normal. Less than 150,000 platelets per microliter indicate a low platelet count. People with thrombocytopenia have low platelet levels. We can bleed heavily and bruise easily if our platelet counts are low.
