Chinese study sets donkey-specific bloodwork intervals

A new study reports Clinical and Laboratory Standards Institute-compliant hematology and serum biochemistry reference intervals for Chinese local donkeys, using 1,163 serum samples and 935 hematology samples collected across five farms. The core finding is straightforward: donkey bloodwork interpretation appears to be more accurate when reference intervals are built for the specific population and management system being served, rather than borrowed from horses or from donkey datasets developed in other countries. That fits with a broader body of donkey clinical pathology research showing that reference intervals can vary by geography, breed or type, age, sex, husbandry, and even analyzer platform.

Why it matters: For veterinary professionals, this is a lab medicine story with practical consequences. Donkeys are already known to differ from horses in clinically important analytes, and prior studies from the U.S., the U.K., Saint Kitts, and Portugal have all reinforced the need for species- and population-appropriate intervals when interpreting CBC and chemistry panels. In settings that serve working equids, production donkeys, or regionally distinct local populations, using mismatched reference intervals can raise the risk of overcalling disease, missing subtle abnormalities, or making poor comparisons over time.

What to watch: The next question is whether these intervals are adopted by Chinese veterinary laboratories and validated across additional donkey breeds, age groups, and management systems. (asvcp.org)
