Table 1 Troponin I and T interpretation

From: Cardiac ischemia in patients with septic shock randomized to vasopressin or norepinephrine

  Troponin I (µg/L) Troponin T (µg/L)
Normal ≤0.5, No myocardial injury <0.05, normal
Weakly positive 0.6 to 2.3, suggestive of myocardial injury 0.05 to 0.09, borderline
0.10 to 0.49, weakly positive
Highly positive >2.3, suggestive of acute myocardial infarction >0.49, positive
