Evaluation of the Freestyle Optium Neo H point-of-care device for measuring blood glucose concentrations in sick calves.

The Freestyle Optium Neo H showed proportional and constant biases relative to the reference method. The glucometer showed poor performance according to criteria recommended by the International Standards Organization and the American Society for Veterinary Clinical Pathology. However, the glucometer determined hypoglycemia with high sensitivity and specificity therefore it might be used to diagnose hypoglycemia in calves with different diseases until calf-specific POC glucometers are developed.
