Platelets are cells produced in the bone marrow, present in the bloodstream, and involved in blood clotting. Their action can prevent bleeding or reduce its duration and intensity.
Low platelet count in diagnosis means that the number of these cells in the blood is below normal. In cases of high platelet count, also known as thrombocytosis, there is a higher than usual quantity of these cells.
In some clinical situations, there may be an increase in the number of platelets, called thrombocytosis.
Thrombocytosis can predispose to the occurrence of thrombosis, which is the formation of clots inside blood vessels, causing their occlusion. In other clinical situations, a decrease in the number of platelets may occur, called thrombocytopenia.
