Platelet-associated antibodies blood test

Thrombocytopenia - platelet antibody; Idiopathic thrombocytopenic purpura - platelet antibody

This blood test shows if you have antibodies against platelets in your blood. Platelets are particles in the blood that help the blood clot. Sometimes the body may produce antibodies that affect its own platelets.

Blood test

Blood is drawn from a vein (venipuncture), usually from the inside of the elbow or the back of the hand. A needle is inserted into the vein, and the blood is collected in an air-tight vial or a syringe. Preparation may vary depending on the specific test.
