Rapid HIT Testing: Are Two Tests Better Than One?

Sunday, June 25, 2023
12:15–1:00 PM ET

Exhibit Hall PT3

Plan to attend this insightful and informative session.


Program Overview

As part of the ISTH Congress 2023, you’re invited to attend our educational Presentation Theater, featuring Dr. Ted Warkentin. He will discuss the ‘clinical-pathological’ anti-platelet factor 4 (PF4) disorder, heparin-induced thrombocytopenia (HIT) and the role of rapid, on-demand HIT antibody testing. To improve the diagnosis of HIT, the use of one versus two rapid tests will be compared and considered.


  • Describe HIT as a “clinical-pathological” anti-PF4 disorder
  • Understand the role of rapid HIT testing as a 5th T in the 4Ts scoring system, utilizing likelihood ratios
  • Discuss the impact of one versus two rapid HIT tests on the improvement of patient outcomes

A Q&A session with Dr. Warkentin will follow his presentation.
