Flow Cytometry

Test Usage

Circulating antibodies to platelets, detected by flow cytometry, are found in the sera of patients with immune-mediated disorders. Platelet antibodies have been associated with ITP and drug-induced thrombocytopenia. Circulating platelet antibodies detected by flow cytometry may recognize platelet-specific glycoproteins or HLA class I antigens (or both).
