The sixth-generation high-sensitivity cardiac troponin T assay identified 61% of patients with concentrations below 13 ng/L at presentation.
-
2
The sixth-generation assay demonstrated a negative predictive value of 99.9% and sensitivity of 99.4% for type 1, 4b, or 4c MI.

Using the sixth-generation assay, 41% of patients were classified as low risk at presentation, compared to 17% with the fifth-generation assay.

The study highlighted the need for more diverse cohorts and prospective studies to confirm the benefits of the sixth-generation assay.
-
5
The sixth-generation assay showed higher cardiac troponin T concentrations than the fifth-generation, indicating they are not interchangeable.
