Comparison of the indicative systems yeast G-6-P dehydrogenase[G-6-PD]/NADP+, Leuconostoc G-6-PD/NADP+ and Leuconostoc G-6-PD/NAD+ showed excellent correlation and no differences in apparent creatine kinase activity with the 2 methods using NADP+. By using NAD+ with the Leuconostoc enzyme, relative recovery of apparent creatine kinase activity is lower due to interference of other serum constituents. The mean value of the relative differences versus methods using NADP+ was 5.8%.
