Effect of non-glucose sugars and haematocrit on glucose measurements with Roche Accu-Chek Performa glucose strips

Venous and capillary whole blood glucose from the fingertip D. Type of Test: Quantitative amperometric assay, glucose dehydrogenase (mutant GDH-PQQ) E. Applicant: Roche Diagnostics Corporation F. Proprietary and Established Names: ACCU-CHEK Performa Blood Glucose Monitoring System

"No coding" of glucose test strips: a roche perspective.

INTRODUCTION Glucose test strips vary slightly from batch to batch. These variations are accounted for by a batch-specific "code": a set of parameters defining the relationship between the signal change induced on the glucose test strip and the blood glucose concentration. METHODS We assessed the impact on accuracy of miscoding the ACCU-CHEK Aviva system across a wide range of glucose test st...

Monitoring neonatal hypoglycemia with the Accu-chek advantage II glucose meter: the cautionary tale of galactosemia.

To the Editor: Hand-held glucose meters are a practical solution for measuring glucose in neonatal intensive care units and special care nurseries because of their portability, the immediacy of results, and minimal blood volume requirements compared with dispatching samples for central laboratory analysis. We have used the Roche Accu-chek Advantage II meter for some time in our neonatal intensi...

Analytical validation of the new plasma calibrated Accu-Chek Test Strips (Roche Diagnostics).

BACKGROUND The Accu-Chek Inform glucose monitor is a point-of-care system for testing blood glucose. New test strips, calibrated to deliver glucose plasma-like values, were launched on the market in May 2005. The aim of our study was to perform analytical validation of these new strips. METHODS We compared the new plasma strips with whole blood strips; results for the plasma strips with plasm...

Toxic levels of acetaminophen produce a major positive interference on Glucometer Elite and Accu-chek Advantage glucose meters.

ied this possibility by performing the enzymatic assay on controls containing increasing concentrations of ACET in the presence of different therapeutic concentrations of NAC (Fig. 1A). Evidently, NAC concentrations $100 mg/L cause a marked negative bias, reaching total suppression of the reaction in the presence of 10 g/L NAC. In contrast, similar concentrations of NAC have no effect on the AC...
