Methodology
Solid-phase enzyme-linked immunoassay
Stability
Room temp: Unacceptable, Refrigerated: 48 hours, Frozen: 7 days
Reference Range
The reference range is determined by the performing laboratory and will show on the report.
Turnaround

Clinical Use
Test includes:
Antibodies to HLA class I antigens and platelet-specific glycoproteins IIb/IIIa, Ib/IX, Ia/IIa, and GP-IV.
Used to screen for the presence of circulating antibodies to platelets (not bound to the platelet surface), that may be associated with the destruction of platelets.
