The 99th percentile is another source of confusion. There are two common ways of determining a cut-point for a diagnostic test (Figure 1). WebA delta troponin of ≥20% increased the specificity of hsTnT from 80.6% to 93.7% but reduced sensitivity from 90.9% to 71.8%. Conclusion: hsTnT was superior to TnT but equivalent to TnI 3 for the diagnosis of AMI. Serial troponin measurement increased test performance. hsTnT was the most likely to be raised at baseline in those with AMI. greensboro urology greensboro nc
