Limitations

This test was developed and its analytical performance characteristics have been determined by Quest Diagnostics. It has not been cleared or approved by the U.S. Food and Drug Administration. This assay has been validated pursuant to the CLIA regulations and is used for clinical purposes.

Reference Range

Platelet Ab, Indirect (IgG) Negative
Platelet Ab, Indirect (IgM) Negative

Clinical Significance

Circulating antibodies to platelets have been associated with immune and drug-induced thrombocytopenia. Elevated levels of platelet - associated antibodies may occur in autoimmune thrombocytopenia, as well as thrombocytopenia associated with carcinoma, AIDS, and connective tissue diseases. Both circulating and associated platelet antibodies may play a role in platelet destruction. Platelet antibodies may consist of a single isotype or any combination of isotypes.
