Platelets help your body form clots to stop bleeding.
Platelets are thiny blood cells that If one of your blood vessels gets damaged, it sends out signals to the platelets. The platelets then rush to the site of damage and form a plug (platelets make a cluster around the damage areas) to fix the damage.
Platelets Facts
Platelets are made in your bone marrow along with your white and red blood cells. Your bone marrow is the spongy center inside your bones. Another name for platelets is thrombocytes. Healthcare providers usually call a clot a thrombus. Once platelets are made and circulated into your bloodstream.
Thrombocytes live in your bloodstream for 8 to 10 days.
Platelet looks like a tiny plate.
Blood test for platletes and WBC ,RBC determination is called a complete blood count (CBC or FBC)
Normal platletes
A normal platelet count is 150,000 to 450,000 platelets per microliter of blood.
bleeding start from your gum's and in the urine (without being cut) develops if a platelet count falls below 10,000 to 20,000. When the platelet count is less than 50,000, bleeding is likely to be more serious.
Low platletes count
Thrombocytopenia. In this condition, your bone marrow makes too few platelets. Or your platelets are destroyed. If your platelet count gets too low, bleeding can occur under the skin as a bruise.
Thrombocytopenia can be caused by many things. These include several medicines, cancer, liver disease, pregnancy, infections, and an abnormal immune system.
High Platletes
thrombocythemia. In this condition, your bone marrow makes too many platelets. People with this condition may have platelet counts of more than 1 millions.
platelets being used by forming clots, or from the platelets not functioning correctly.
Other symptoms can include blood clots that form and block blood supply to the brain or the heart.
thrombocytosis. This is another condition caused by too many platelets. Secondary thrombocytosis is more common. It's not caused by a bone marrow problem. Instead, another disease or condition stimulates the bone marrow to make more platelets. Causes include anemia. infections.inflammation, some types of cancer, and reactions to medicines.
