Despite its specificity, cTnI has some limitations. It may not detect very early stages of myocardial infarction, as it takes several hours for cTnI levels to rise following cardiac injury. Additionally, factors such as renal failure, strenuous exercise, and certain medical conditions can lead to elevated cTnI levels, potentially resulting in false-positive results. Therefore, cTnI levels should be interpreted in conjunction with clinical findings and other diagnostic tests.
