A comparison of accuracy and estimated cost of methods for home blood glucose monitoring

Venous serum glucose concentrations determined by a laboratory hexokinase
technique were compared over a wide range of glucose concentrations with
concentrations of capillary blood glucose determined by three reflectance
meter techniques currently available in the United States (Eyetone and
Dextrometer, Ames Company; StatTek, Bio-Dynamics BMC) and by visual
interpretation of reagent strips (Chemstrip bG, Bio-Dynamics BMC). The
Chemstrip bG reagent strip was read by patients, nurses, and a physician.
In all cases, there was an excellent correlation between laboratory serum
glucose concentrations and reflectance meter blood glucose determinations
(r = 0.90-0.94, P less than 0.0001) or visual interpretation of Chemstrip
bG (r = 0.85-0.92, P less than 0.0001). Chemstrip bG appears to be the
least expensive method of glucose measurement. This method offers
additional advantages in not requiring a reflectance meter, which needs
frequent recalibration and other ancillary equipment for blood glucose
determination.
