BACKGROUND The purpose of this study was to determine serum reference values for creatine kinase (CK), aspartate aminotransferase (AST) and lactate dehydrogenase (LDH) in captive-born and wild-caught owl monkeys to assess their usefulness for diagnosing myocardial disease. METHODS Blood samples were collected for CK, AST and LDH determinations. In(More)
