title: The normal range for serum creatine phosphokinase.
abstract: The present investigation establishes the normal range for serum creatine phosphokinase (CPK) in 292 blood donors, using a commercially available enzyme assay kit. The results illustrate the non-Gaussian nature of the distribution and emphasize the necessity for the use of non-parametric statistical methods. A marked sex difference and the presence of apparently normal individuals with increased levels of CPK was also noted and discussed.
