Cardiac troponin I (cTnI), a protein in myocardial fibers, is one of the important biomarkers for diagnosing myocardial infarction. When cardiomyocytes are damaged, cTnI is released into the bloodstream, so cTnI testing can help diagnose cardiovascular diseases such as myocardial infarction and myocarditis. Anti-cTnI antibody is an antibody used to detect cTnI, with high sensitivity and specificity, which can be used to quickly and accurately diagnose myocardial infarction. The advantage of anti-cTnI antibodies is that they can provide rapid and accurate diagnostic results, help doctors take timely treatment measures, and improve the survival rate and quality of life of patients.
