Effects of sample temperature on the concentrations of glucose and β-OH butyrate measured by the Precision Xtra meter in plasma from periparturient dairy cattle

Abstract

Early and accurate diagnosis of hypoglycemia and hyperketonemia is helpful in the diagnosis and treatment of ketosis in periparturient dairy cattle. The results of a preliminary study recently indicated that the glucose concentration [glue] and β-OH butyrate concentration [BHB] measured by the Precision Xtra meter was impacted by sample temperature when temperature <89.6° (< 32°C). The objective of this study was to fully characterize the effects of sample temperature on the accuracy of the Precision Xtra® for measuring [glue] and [BHB].
