The blood platelets are the smallest cells of the blood, averaging about 2 to 4 μm in diameter.
What happens when platelets are too high?
If your platelet count is too high, blood clots can form in your blood vessels. This can block blood flow through your body. Thrombocythemia refers to a high platelet count that is not caused by another health condition. This condition is sometimes called primary or essential thrombocythemia.
What does it mean when red and white blood count is low?
Aplastic anemia occurs when your bone marrow doesn't make enough red and white blood cells, and platelets. Having fewer red blood cells causes hemoglobin to drop.
