Above the range
What causes a high Troponin I?
Normal range < 0.04 (assay-dependent) ng/mL (< 0.04 µg/L SI). Specimen: Serum or plasma. See the full Troponin I reference page for critical values and nursing considerations.
What is the normal range for Troponin I?
The standard teaching reference range for Troponin I is < 0.04 (assay-dependent) ng/mL in conventional units, or < 0.04 µg/L in SI units. This value is measured in serum or plasma.
| Specimen | Serum or plasma |
|---|---|
| Conventional range | < 0.04 (assay-dependent) ng/mL |
| SI range | < 0.04 µg/L |
| Critical value | Any elevation above the 99th percentile signals myocardial injury |
