Cardiac Markers
Normal range < 0.01 (assay-dependent) ng/mL (< 0.01 µg/L SI). Specimen: Serum or plasma.
Also known as: cTnT, cardiac troponin T.
This result is reported qualitatively or as a one-sided threshold rather than a two-sided numeric band.
| Specimen | Serum or plasma |
|---|---|
| Conventional range | < 0.01 (assay-dependent) ng/mL |
| SI range | < 0.01 µg/L |
| Conversion factor | ×1 (conventional → SI) |
| Critical value | Elevation above the assay's 99th percentile indicates myocardial injury |

The standard teaching reference range for Troponin T is < 0.01 (assay-dependent) ng/mL in conventional units, or < 0.01 µg/L in SI units. This value is measured in serum or plasma.
A commonly taught critical (panic) value is Elevation above the assay's 99th percentile indicates myocardial injury. Critical results are reported to the provider immediately under your facility's policy.
