Platelets are tiny blood cells that help your body form clots to stop bleeding. If one of your blood vessels gets damaged, it sends out signals that are picked up by platelets. The platelets then rush to the site of damage and form a plug, or clot, to repair the damage.n this condition, your bone marrow makes too many platelets. People with thrombocythemia may have platelet counts that exceed 1 million. Symptoms can include blood clots that form and block blood supply to the brain or the heart. The cause of thrombocythemia is unknown.
The platelet count is a test that determines the number of platelets in a person's sample of blood. When there is an injury to a blood vessel or tissue and bleeding begins, platelets help stop bleeding in three ways. They: 1  Adhere to the injury site. 2  Clump together (aggregate) with other platelets.n excess of platelets can cause excessive clotting or sometimes bleeding if the platelets are not functioning properly. However, people with too many platelets often have no signs or symptoms, so the condition may be found only when a platelet count is done as part of a health check or for other reasons.
