Platelet associated antibodies
Normal Values
A negative test is normal. Normal value ranges may vary slightly among different laboratories. Talk to your doctor about the meaning of your specific test results.
What do Abnormal Results Mean?
Abnormal results show that you have antiplatelet antibodies. These are proteins made by the body that attach to platelets and destroy them. This causes a low platelet count, which can lead to excessive bleeding.
Antiplatelet antibodies may appear in the blood for unknown reasons (idiopathic thrombocytopenic purpura), or as a side effect of certain drugs such as heparin. These drugs can sometimes cause the immune system to identify its own platelets as abnormal or foreign, and attack them.
