The 99th percentile and imprecision of point-of-care cardiac troponin I in comparison to central laboratory tests in a large reference population

While the cTnI POCT showed analytical performance comparable to CLT, the results of the cTnT assay on the same device did not suffice to determine a reliable 99th percentile. The present evaluation supports the usage of the cTnI POCT, but application of the cTnT POCT needs further evaluation.
