Glycosylated haemoglobin in dogs: study of critical difference value

Abstract Measurement of glycated proteins can be of use in diagnosis and monitoring of diabetic dogs. Its use in monitoring can be facilitated by comparison of results with a reference interval derived from levels in normal dogs. In this study, a commercial immunoturbidometric assay was used to measure glycosylated haemoglobin in 15 normal dogs over a 5-week period. Following statistical analysis of the results a critical difference value of 0·38 per cent was obtained.
