Troponin sensitivity and specificity

WebObjective European guidelines recommended a uniform upper reference limit of high-sensitivity cardiac troponin T (hsTnT) to rule out non-ST segment elevation myocardial infarction. Our study aimed to provide a hsTnT reference distribution and to assess the specificity of the 14 ng/L cut-off value in the mobile population ≥70 years of age. WebTnI was detectable in 75% and 57% of the apparently healthy population using the lower (1.1 ng/L) and upper (1.9 ng/L) limit of the LoD range provided by the ARCHITECT STAT hs-TnI package insert, respectively. The 99th percentile values were gender dependent.

WebJun 13, 2013 · Troponin is a protein complex of three subunits— T (TnT), I (TnI), and C (TnC)—that is involved in the contractile process of skeletal and cardiac muscle. TnC is expressed in both cardiac and skeletal muscle; under normal conditions, cardiomyocytes express cardiac-specific forms of TnT and TnI (cTnI and cTnT). WebThe cardiac troponins T and I (cTnT and cTnI) have been found to have excellent sensitivity and specificity and are superior to creatine kinase-MB (CK-MB) as indicators of myocardial necrosis. 1 Using cTnT or cTnI as a diagnostic marker, the positivity rate in studies has varied from 20–48%, with death and acute myocardial infarction (MI) varying … tahiti government travel website https://ewcdma.com
