Discussion

Evaluation shows calibration with 5B9 did not enhance optical density results in detecting HIT, suggesting alternatives may be needed.

HIT diagnosis was confirmed in 43 of 170 patients, with a clear distinction based on OD values.
The assay showed a negative predictive value of 98% and a positive predictive value of 83% when using an OD threshold of 1.05.
Calibration with 5B9 provided similar performance metrics as using standard OD measurements without improvement.
Post-test probabilities indicated effectiveness in ruling out HIT at lower OD values and confirming it at higher levels.

Pouplard et al. (2025) studied this question.
