Troponin T is another heart muscle protein used to detect heart injury. High-sensitivity tests can detect very small amounts.
- Normal range (adults)
- Below 0.01 ng/mL (below 10 ng/L)
- Sample
- Blood
- Fasting
- Not usually needed
- Also called
- Cardiac Troponin T, cTnT, TnT, High Sensitivity Troponin T, hsTnT
Troponin T normal range
| Group | ng/mLConventional units: US, South Asia | ng/LSI units: UK, Europe, Australia, international |
|---|---|---|
| Adults | Below 0.01 | Below 10 |
Cut-offs depend on the exact assay. Always use the reference limit printed on your report.
Your report may use either unit system; labs in the Gulf often print both. Ranges also vary slightly between laboratories, so the range printed on your own report is the one to go by.
Why is the Troponin T test done?
It is used in emergency departments to diagnose or rule out a heart attack.
What does a high Troponin T level mean?
A raised troponin T means heart muscle damage. A rising pattern with chest pain indicates a heart attack.
Common causes
- Heart attack
- Myocarditis
- Heart failure
- Kidney disease
- Sepsis or pulmonary embolism
Diet and lifestyle tips
- After recovery: heart-healthy diet, low salt, no smoking, regular activity as advised by your cardiologist
