A test for platelet-associated antibodies shows whether you have antibodies that are directed against platelets in your blood.

A blood sample is needed. For information on how this is done, see: Venipuncture

No special preparation is necessary for adults.

When the needle is inserted to draw blood, some people feel moderate pain, while others feel only a prick or stinging sensation. Afterward, there may be some throbbing.

This test may be ordered when you have a low platelet count (thrombocytopenia). It is used to detect antibodies against platelets.
