Reference intervals for some clinical chemical parameters in the marmoset (Callithrix jacchus): Effect of age and sex

Abstract

Reference intervals for some clinical chemistry parameters in the marmoset were calculated. The effects of age (250-300 days compared with 500-550 days) and sex on the values found was investigated. Alkaline phosphatase levels decreased with age, young males having higher plasma levels than young females, but no sex differences were discernible for older animals. Levels of ɤ-glutamyl transpeptidase and sorbitol dehydrogenase were higher in older males than in younger females. Higher plasma iron levels were found in the males with increasing age. Age and sex effects for protein and albumin were interactive and further interpretation was therefore difficult. No significant age or sex effects were seen for cholinesterase, acetylcholinesterase, isocitrate dehydrogenase, malate dehydrogenase, lactate dehydrogenase, glutamate dehydrogenase, aspartate amino transferase, alanine aminotransferase or bilirubin. © 1984, Royal Society of Medicine Press.
