Aka: Troponin T, Troponin T Assay
- See Also
- Troponin
- Troponin I
- Ultrasensitive Troponin T
- Serum Cardiac Markers
- Epidemiology
- Test Sensitivity: 94% of Myocardial Infarctions
- Test Specificity: Low (22% have Unstable Angina)
- See Troponin for false possible causes
- Labs: Timing Following Acute Myocardial Infarction
- Serum levels increase within 4-8 hours of MI onset
- Serum levels peak at 12 to 48 hours
- Serum levels are elevated for 4-10 days after MI
- Advantages
- Highly sensitive for detecting Myocardial Infarction
- Level may also help to risk stratify afterward
- Qualitative test run in 10 minutes
- Disadvantage
- Less specific than Troponin I
- Elevated in Unstable Angina
- Elevated in Chronic Renal Failure
- Levels stay elevated for days
- Unable to time acute coronary event
