Abstract
Objective- To evaluate agreement of 3 models of portable blood glucose
meters (PBGMs; 2 designed for use with human samples and 1 designed for
veterinary use) with a laboratory analyzer for measurement of blood
glucose concentrations in ferrets (Mustela putorius furo).

Design- Evaluation study.

Animals- 52 ferrets.

Procedures- Samples were analyzed with 4 PBGMs (whole blood) and a
laboratory analyzer (plasma). Two PBGMs of the model designed for
veterinary use were tested; each was set to a code corresponding to
canine or feline sample analysis throughout the study. Agreement and
bias between measurements obtained with the PBGMs and the laboratory
analyzer were assessed with Bland-Altman plots. Linear regression
analysis was performed to evaluate associations with venipuncture site
by comparison of central (jugular) and peripheral (lateral saphenous
or cephalic) venous blood samples.

Results- Plasma glucose concentrations measured with the laboratory
analyzer ranged from 41 to 160 mg/dL. Results from the PBGM for
veterinary use coded to test a canine blood sample had the greatest
agreement with the laboratory analyzer (mean bias, 1.9 mg/dL); all
other PBGMs significantly underestimated blood glucose concentrations.
A PBGM designed for use with human samples had the least agreement
with the laboratory analyzer (mean bias, -34.0 mg/dL). Blood glucose
concentration was not significantly different between central and
peripheral venous blood samples for any analyzer used.

Conclusions and Clinical Relevance- Significant underestimation of
blood glucose concentrations as detected for 3 of the 4 PBGMs used in
the study could have a substantial impact on clinical decision making.
Verification of blood glucose concentrations in ferrets with a
laboratory analyzer is highly recommended.
