15334: Heparin-Induced Plt Ab w/ Rflx to SRA Unfractionated Heparin Print View
Heparin-Induced PLT AB      
Patient O.D.      

PRIMARY
1 Serum Red Top 1 (0.5) mL   Frozen - 6 Month(s)  
ALTERNATE
  Plasma Citrated 1 (0.5) mL   Frozen - 6 Month(s)  

Diagnosis of Heparin Induced Thrombocytopenia is based on clinical criteria but serological confirmation is often necessary. The ELISA assay measures the Platelet Factor 4/Heparin Complex to IgG. When the ELISA test is positive, testing by Serotonin Release Assay (a platelet activation assay) is more predictive of thrombocytopenia and thrombosis.

For serum:
Centrifuge red top tube 15 minutes at approximately 1500 g as
soon as possible after clotting.
For plasma:
Centrifuge blue top tube 20 minutes at approximately 2500 g. Remove
plasma from the cells as soon as possible.
