Quantitative bedside testing of troponin T: is it equal to laboratory testing? The Cardiac Reader Troponin T (CARE T) study.

The progressive evolution of cardiac marker testing in patients with acute coronary syndromes has extended their role into risk stratification and guidance of therapeutic regimen. To provide utilization of cardiac markers around the clock and facilitate the diagnostic work-up of patients with acute chest pain in the emergency room, a point-of-care system for quantitative troponin T and myoglobin testing in whole blood samples was developed. Aim of this multicenter study was to evaluate bedside quantitative determination of myoglobin and troponin T in chest pain patients in a clinical routine setting.
