PF4 Enhanced® and PF4 IgG Assay​

Detect harmful antibodies that cause Heparin Induced Thrombocytopenia (HIT).

Detect harmful antibodies that cause Heparin Induced Thrombocytopenia (HIT).

The PF4 family of products detect heprin-induced PF4 antibodies in multiple kit formats allowing the flexibility to detect either IgG/A/M or IgG specific antibodies.

Heparin-Induced Thrombocytopenia (HIT) is an adverse reaction after prolonged exposure to unfractionated or Low Molecular Weight Heparin. Work by Warkentin et al. suggests a direct link between the OD value, e.g. the titer of the Antibody, and the likelihood that a patient has HIT or could develop it if exposure to heparin is not discontinued.

  • Reduce false positives with the heparin neutralization step
  • Assure confidence with high sensitivity
  • ELISA assay using polyvinyl sulfonate (PVS)
