A New Generation of Biomarkers Tests of Myocardial Necrosis: The Real Quality a Physician can get from the Laboratory

Background Recent guidelines recommended by ESC, ACC, AHA, and WHF concerning biomarkers of myocardial necrosis also apply to the work of clinical laboratories. Methodological modification for tests used in determining cardiac biomarkers reduced the time of the analytical procedure to 9 min (STAT version of the tests). We decided to determine and compare analytical quality of the tests in standard and STAT versions for determining serum level: troponin T, MB isoenzyme of creatine kinase, and myoglobin, as well as to verify whether the TnThs STAT test meets the following requirements: CV <10% at the level close to diagnostic, equal to the 99th percentile of reference population, and turnaround time <60 min.
