On January 4th 2016, LifeLabs in Victoria will be implementing high sensitivity Troponin T testing (hsTNT) and discontinuing the previous Troponin I test (cTnI). While this will align our testing with Victoria laboratories in the Vancouver Island Health Authority, note that some VIHA sites north of the Malahat may still be using cTnI.
The hsTNT assay reliably measures small elevations of this cardiac marker which are undetectable using previous troponin assays. Note that the units of measure for hsTNT (ng/L) provide numerical results that are 1000x greater than for the previous cTnI (ug/L).
