Total cTnT, long cTnT, and troponin ratio in patients with NSTEMI (n = 30) and ESRD (n = 37). Total cTnT and long cTnT concentrations were measured with the commercial hs-cTnT assay and the novel UCL long cTnT assay, respectively. The troponin ratio was calculated by dividing the long cTnT result by the total cTnT result.
