Age-related changes in serum copper and zinc concentrations were evaluated in approximately 800 Beagle dogs. A 20% increase with age was established for both elements. Seasonal variation was also found to have a marked effect on serum zinc with the values positively correlated to ambient temperature. In contrast, serum copper was not affected by temperature. Hemolysis, but not lipemia, was found to affect analytical results.
