Precision of point-of-care glucometry in hypoglycaemic horses

Point-of-care (POC) glucometry is commonly used in horses; however, measurement error with this method when analysing hypoglycaemic samples (<4mmol/L) is unknown. The objective of this study was to determine the precision and accuracy of glucometry in hypoglycaemic horses in comparison to a laboratory method of glucose measurement (LAB). Repeatability coefficients were 0.47mmol/L for POC and 0.09mmol/L for LAB, and coefficients of variation were 10% and 2.11%, for the POC and LAB methods, respectively. Systemic bias with the POC method was present, with a mean bias of -0.26mmol/L (95% limits of agreement: -0.88 - 0.37) in comparison to LAB, and <70% ...
