Acquired platelet function defect

Acquired qualitative platelet disorders; Acquired disorders of platelet function

Acquired platelet function defects are conditions that prevent clotting elements in the blood called platelets from working as they should. The term acquired means these conditions are not present at birth.

Blood clot formation

Blood clotting normally occurs when there is damage to a blood vessel. Platelets immediately begin to adhere to the cut edges of the vessel and release chemicals to attract even more platelets. A platelet plug is formed, and the external bleeding stops. Next, small molecules, called clotting factors, cause strands of blood-borne materials, called fibrin, to stick together and seal the inside of the wound. Eventually, the cut blood vessel heals and the blood clot dissolves after a few days.

Blood clots

Blood clots (fibrin clots) are the clumps that result when blood coagulates.
