A Comparison Study Between Point‐of‐Care Testing Systems and Central Laboratory for Determining Blood Glucose in Venous Blood

Abstract

The POCT system cannot replace the central laboratory system as a provider of a standard result in clinical diagnosis. It can only be used as a screening test.

Utility of point‐of‐care vs reference laboratory testing for the evaluation of glucose levels

“…These findings are different from previous recent studies that showed similar measurements for the two methods [10,11,14,22]. These findings are different from previous recent studies that showed similar measurements for the two methods [10,11,14,22].…”

Previous studies have demonstrated favourable overall performance of various point-of-care glucose meters in determining glucose values in venous blood samples as compared to laboratory reference values in hospital settings [10,11,[13][14][15][16]; however, data on point-ofcare glucose meter validity according to glycaemic status are limited; therefore, the objective of the present study was to assess the level of agreement of point-of-care measures of venous whole blood glucose with laboratory glucose measures in defining glycaemic status.

“…The conversion of point-of-care glucose values from fresh capillary blood and from venous whole-blood samples (e.g. tests used by healthcare professionals in clinical or hospital settings) to laboratory tests are subject to random measurement errors [9][10][11]. The American Diabetes Association (ADA) recommended an acceptable error range of up to 15% between the values obtained by glucose meter to be tested and those obtained by the laboratory reference method, which was modified subsequently to a maximum error range of up to 5% [12].…”
