Definition An acquired platelet function disorder refers to an abnormality in the clotting ability of the platelets which develops sometime after birth.
Platelets are a type of cell found in the blood.
Various disorders can affect the normal function of platelets, which is primarily to help blood clot. Platelets, along with a number of other substances in the blood, help blood to clot. When a person cuts himself or herself, blood must clot, or turn solid, to stop the bleeding. When platelets lose their ability to function for any reason, abnormal bleeding and bruising may occur. An acquired platelet function disorder may cause no symptoms at all.
