Rand et al. said:
NB. The blood glucose values were based on using portable glucose meters (Ascensia Contour, Bayer,
Leverkusen, Germany; Accu-Chek Aviva, Roche Diagnostics, Basel, Switzerland) which use ≤0.6 μL of
blood per test. These meters measure blood glucose concentration in whole blood and are calibrated for
use with human blood. Measurements from meters calibrated for human blood which provide plasmaequivalent
values are approximately 10% higher.
NB. It is very important to note that blood glucose concentrations measured using a whole blood
glucose meter calibrated for human blood may measure 30-40% lower in the low end of the range than
glucose concentrations measured using a serum chemistry analyser or a plasma-equivalent meter calibrated
for feline use. Therefore, if using a meter calibrated for feline use (eg. AlphaTRAK, Abbott
Laboratories, CA, USA), or a serum chemistry analyzer, add approximately 30 mg/dL (1.7 mmol/L)
to the target glucose concentrations (see Table 3B). For example, a target > 50 mg/dL (2.8
mmol/L) becomes > 80 mg/dL (4.4 mmo/L) when using a meter calibrated for feline use. Instead of
aiming for 50-100mg/dL (2.8-5.6 mmol/L) , aim for 80-130 mg/dL (4.4-7.2 mmol/L [round numbers
4.5-7.0 mmol/L). Meters calibrated for feline use may read higher or lower than the actual value, in
contrast to consistently lower readings for meters validated for human blood.
