When to use
Apply assay-specific cut-offs and the clinical context rather than a single fixed value.
How it works
Troponin: 99th-percentile URL + dynamic rise/fall = type 1 MI. NT-proBNP rule-in for acute HF: > 450/900/1800 by age. D-dimer age-adjusted cut-off = age × 10 µg/L FEU over 50.
Key points
- Cut-offs and 0/1h deltas are assay-specific.
- Chronic troponin elevation occurs in CKD and chronic HF.
- D-dimer rules out VTE only at appropriate pretest probability.
- BNP is raised by renal impairment/AF and lowered by obesity.
