How often are troponins repeated
NettetTroponin, or the troponin complex, is a complex of three regulatory proteins ( troponin C, troponin I, and troponin T) that are integral to muscle contraction [2] in skeletal muscle and cardiac muscle, but not … NettetCMFT currently uses the high sensitivity troponin T assay from Roche Diagnostics (hs-cTnT). In patients whose symptoms and/or signs lead treating clinicians to suspect a diagnosis of acute coronary syndrome, hs-cTnT should be measured at the time of admission or as soon as possible following the onset of symptoms.The test should be …
