Point-of-care beta-hydroxybutyrate testing for assessing diabetic ketoacidosis severity prior to treatment in the emergency department.Diabetes Res Clin Pract. 2011 Dec; 94(3):e86-8.DR
We prospectively evaluated the correlation between point-of-care β-OHB values and DKA severity at time of initial diagnosis in 54 patients. The correlation coefficients between β-OHB and pH, bicarbonate and anion gap were 0.33, 0.25 and 0.16, respectively. We conclude that point-of-care β-OHB absolute values cannot reliably assess DKA severity.
