Test Code LAB747 High-Sensitivity Troponin I 

Important Note

Cardiac Troponin is the preferred biomarker for the dection of myocardial infarction based on improved sensitivy and supertion tissue-specificity compared to other available biomarkers of necrosis, including CKMB, myoglobin, LDH , and others. The high tissue specificiity of cTnl measurements is beneficial for identifying myocardial infarction in clinical conditions involving skeletal muscle injury resulting from surgery, trauma, extensive exercise, or muscular disease.
