Troponin T (TnT)

Cardiac Markers

Normal Reference Ranges

Adult

< 0.01 ng/mL

Pediatric

N/A ng/mL

Clinical Significance

Highly sensitive marker for cardiac injury. Note that Troponin T can be chronically elevated in patients with severe renal failure, making serial changes more important than the absolute number.

Causes of High

  • Acute Myocardial Infarction
  • Myocarditis
  • Pulmonary Embolism
  • End Stage Renal Disease (ESRD)

Causes of Low
