Troponin i vs troponin t specificity
Websuffer from low cardiac specificity and sensitivity (2–6). Test systems for cardiac troponin T and troponin I (cTnI) provide the highest cardiac specificity and analytical sensitivity for the detection of myocardial injury (7–12). These allow early identification of patients with acute myocardial infarction (AMI), and in one-third of patients WebMAIN RESULTS: Sensitivity increases for both troponin T and I from 10% to 45% within 1 hour of the onset of pain (depending on the cutoff) to more than 90% at 8 or more hours. Specificity declines gradually from 87% to 80% from 1 to 12 hours after the onset of chest pain for troponin T and is approximately 95% for troponin I.
