Changes to troponin assay: from Troponin-I to High Sensitivity Troponin

Our troponin assay recently changed from Troponin-I (TnI) to High Sensitivity Troponin-I (hs-TnI). The new assay is approximately 4.5x more sensitive to the presence of Troponin in blood samples than the previous assay.  See below for the hs-TnI algorithm and critical value levels.

How do the new hsTroponin values compare to our conventional assay?

Convert by a factor of 1000! eg 0.05 on the old scale is around 50 on the hsTroponin scale
