Heparin-Induced Thrombocytopenia - SRA

Attention: Due to a national sole-source supplier issue, this assay is currently on a reduced run schedule of two days per week. While this modified schedule will continue to meet our published turnaround time, for a more time-sensitive functional assay, consider the PEA (Order Code: 5502) with a 24 hour turnaround time. This test is designed to detect heparin-dependent platelet antibodies in the serum from patients suspected of having Heparin-Induced Thrombocytopenia (HIT).
