Abstract
A method of detecting heparin-induced antibodies to complete a diagnosis of heparin-induced thrombocytopenia (HITP) is disclosed. This method comprises the first step of attaching a glycosaminoglycan to a solid support, wherein the glycosaminoglycan is attached to the solid support only at the reducing end of the molecule (unidirectionally). Platelet factor 4 is then bound to the glycosaminoglycan forming a complex having an epitope recognizable by antibodies generated in an HITP immune response. Human blood plasma or serum from a patient suspected of having HITP is exposed to the complex and the complex is analyzed to determine if HITP-related antibodies are present. A device and kit used in performing the diagnostic assay are also disclosed.
