Total serum creatine kinase and isozyme concentrations in the owl monkey

Abstract

Serum samples from 62 owl monkeys were analyzed to determine concentrations of creatine kinase activity and isozymes. Fifty monkeys were determined to be clinically normal, while twelve had cardiac disease. Findings showed that the data had a non-normal distribution. Based on nonparametric tests, significant differences were not observed between sexes or animals with and without cardiac disease, indicating that CK activity and isozymes are not reliable indicators of myocardial disease in the owl monkey. Reference values presented are only intended as a guide. Each laboratory should determine its own reference values.
