The measurement of beta-hydroxybutyrate (BOHB) carries high significance for the diagnosis, prognosis as well as treatment decisions in canine and feline diabetic ketoacidosis. The aim of this study was to establish clinically usable cut-off values for BHOB measurements in dogs and cats using the glucometer GlucoMen®LX Plus. We measured BOHB with the GlucoMen®LX Plus in 4 patient groups (diabetic ketoacidosis, diabetic non-ketoacidic, catabolic non-diabetic status, control). These were classified based upon medical history and laboratory findings (pH, glucose-, HCO3 - concentrations, anion gap). The data was analyzed in a ROC-curve-analysis in order to create cut-off values. A total of 47 dogs and 55 cats were included into the study. In the differentiation between the two diabetic groups, cut-off values for dogs and cats amounted to 2.55 mmol/l and 4.05 mmol/l, respectively. Here, good sensitivity (100 %) and specificity (82 % and 100 %, respectively) were attained. In the comparison of the catabolic non-diabetic status group and the individuals with diabetic ketosis, the analysis resulted in a cut-off value of 0.25 mmol/l in dogs and 0.25 mmol/l in cats, carrying poor sensitivity (58 % and 59 %, respectively) and specificity (90 %). Measurements with the GlucoMen®LX Plus are suitable for a reliable differentiation between ketoacidosis and ketosis in dogs and cats. Here, the determined cut-off values carried high sensitivity and specificity. A distinction between non-diabetic catabolic individuals and patients with diabetic catabolic states, however, cannot be achieved with adequate consistency. The established cut-off values aid in the treatment decision-making process as well as the assessment of prognosis and treatment success in diabetic ketoacidosis. In representing a point of care technique, the method allows for direct owner communication of the results and immediate adjustment of the treatment regime. Concerning the initial diagnosis or a differentiation between non-diabetic and diabetic catabolic states, however, the presented method alone is not sufficient, therefore additional diagnostic procedures are warranted in order to ascertain a correct diagnosis.
