WebTroponin testing may have a limited role in primary care in the following scenarios: low-risk patients in whom symptoms have completely resolved 24 hours prior to presentation. atypical symptoms with a low likelihood of ACS, where troponin testing may essentially ‘exclude’ ACS to cover clinical uncertainty. WebThe measurement of the cardiac troponins (cTn), cardiac troponin T (cTnT) and cardiac troponin I (cTnI) are integral to the management of patients with suspected acute coronary syndromes (ACS). Patients without clear electrocardiographic evidence of myocardial infarction require measurement of cTnT or cTnI. It therefore follows that a rapid …
