Troponin I (cTnI) Rapid Test

Various clinical studies suggest that troponin levels are elevated after an episode of Myocardial Infarction or Ischemic Damage. Measuring the levels help form or exclude a diagnosis of an MI event.

Interpretation of Troponin I values

A positive troponin result is not always indicative of MI. Other conditions resulting in myocardial cell damage can contribute to elevated cardiac troponin I levels. These conditions include, but are not limited to myocarditis, cardiac surgery, angina, unstable angina, congestive heart failure and non-cardiac related causes, such as, renal failure and pulmonary embolism.

Risk Stratification Analysis of Acute Coronary Syndrome -

Because of its cardiac specificity and sensitivity, cTnI has been used as reliable marker in evaluating patients with unstable angina, a conditions implying increased risk of MI and sudden death. Unstable angina patients with minimal values of cTnI are predicted to have a higher risk of short-term mortality. As the cTnI value progressively increases, the risk of mortality increases, presumably because the amount of myocardial damage also increases.
