A notable difference in the two Ad Meter results was the appearance in the public's top 10, in fourth place, of a commercial for the Chrysler Group, "It's Halftime in America," which featured Clint Eastwood.
To validate theory and demonstrate the passive flux meter, results of multiple box-aquifer experiments are presented and discussed.
Investigate the interference of Virox® disinfectant wipes containing hydrogen peroxide with Lifescan SureStep Flexx® glucose meter results.
A spore preparation was adjusted to a 0.5 McFarland standard with a Microscan turbidity meter, resulting in a 1 x 10 CFU spores/mL suspension.
The difference between glucose meter results, either at the bedside or in the laboratory, compared to the laboratory analyzer ranged from -29% to 39%and-32%21%to 21%, respectively.
A later report, which also studied arterial blood from ICU patients, measured glucose in 239 samples by a portable meter and by a laboratory method and found that the meter results did not meet the CLSI/ISO criteria (142).
In a 2005 study of ICU patients (140), the agreement of meter results with accredited laboratory results was poor: Among 767 paired results, the 95% limits of agreement were +2.4 to −1.5 mmol/L (+43.1 to −27.2 mg/dL).
Despite these good correlations Figure 1 shows that 42% and 30% of glucose meter results, for RN PCx and LAB PCx compared to PG results respectively, were outside ± 15% total error limits.
We evaluated the theoretical impact on insulin titration by comparing glucose meter results with the hexokinase reference method on a dynamic sliding scale targeting a glycemia of 80 to 130 mg/dl.
The Passing-Bablok regression equations and correlations for the blood glucose meter results compared to the laboratory value were: LAB PCx = 1.08 PG –.58, r =.95; RN PCx = 1.18 PG –.55, r =.91.
Common experience tells us that the majority of patients using meters for SMBG are unaware of the magnitude of the potential inaccuracy of results, and we suspect that many health care providers also tend to ascribe greater accuracy than is warranted to portable glucose meter results.
