An evaluation of commercial kits for creatine phosphokinase assay.
1. The evaluation of seven colorimetric and twelve kinetic or ultra-violet (UV) creatine phosphokinase (CPK) kit methods for their reliability as a diagnostic tool in clinical laboratories has revealed that over 35% of such commercial products readily available in Canada do not yield reliable results. 2. Six out of seven colorimetric kits failed to meet the criteria of minimum reliability as did one of the twelve UV kinetic kits.
