Default Re: Blood Glucose Meters, Testing, Curves

A recent study of six blood glucose meters reflects favorably on the OneTouch Ultra.

ACVIM 2008 Abstract

Evaluation of Six Portable Blood Glucose Meters in Dogs.

The purpose of this study was to evaluate six portable blood glucose meters (PBGMs) - AlphaTrak, OneTouch, Elite XL, AccuChek, Precision, Contour - for use in dogs. One hundred fifty-eight venous blood samples were asayed for glucose using all PBGMs in randomized order and by a reference hexokinase method. Results from the PBGMs and reference hexokinase method (HM) were compared.

HM blood glucose concentrations ranged from 41 to 639 mg/dl. There was excellent correlation between PBGMs and HM results (table). Results were consistently low for 4 PBGMs compared with HM results. High and low results were common with the AlphaTrak. The difference in results between PBGMs and HM increased as blood glucose concentrations increased. Difference in results between PBGM and HM were significantly (p<0.0001) less for the AlphaTrak and OneTouch and significantly (p<0.01) higher for the Contour compared with other PBGMs. Problems with correct identification of hypoglycemia (<70 mg/dl), normoglycemia (70-120 mg/dl), and hyperglycemia (>200 mg/dl) varied between PBGMs (table).

Percent Incorrect from Reference Range
AlphaTrak -- 18
OneTouch -- 21
EliteXL -- 45
AccuChek -- 45
Precision -- 49
Contour -- 73

Results of this study support use of the AlphaTrak and OneTouch glucose meters based on significantly closer results with HM.
