Overview

The 4Ts scoring system has diagnostic value.[1]

  • 0 to 3 points: low probability
  • 4 to 5 points: intermediate probability
  • 6 to 8 points: high probability

The American Society of Hematology, as part of the Choosing Wisely program, states[2]:

"Don’t test or treat for suspected heparin-induced thrombocytopenia (HIT) in patients with a low pre-test probability of HIT."
