Implication

Prospective diagnostic study demonstrates misclassification risks with standard testing algorithms in suspected heparin-induced thrombocytopenia, highlighting the need for improved workflows.

Key Points

Clinical implementation of the recommended diagnostic algorithm for suspected heparin-induced thrombocytopenia misclassifies a substantial number of patients.
Among 1318 evaluated patients, the recommended diagnostic algorithm showed 15 false-negative findings at 13.5% and 50 false-positive findings at 4.1% versus 4Ts score.
This prospective diagnostic study using heparin-induced platelet activation as reference highlights that improved workflows are needed to avoid delayed diagnosis.
