Implication

Randomized trial demonstrates accurate quantification of 1,5-anhydroglucitol in diabetic samples, suggesting improved biomarker measurement.

Key Points

This research aims to develop an ATP-independent system to efficiently remove glucose interference in biomarker quantification, specifically for 1,5-anhydroglucitol.
Engineered a thermodynamic-driven recycling system using glucose dehydrogenase and glutamate dehydrogenase.
Evaluated efficiency in water, artificial urine, and serum with glucose concentrations ranging from 0-100 mM.
Validated the system's effectiveness for determining 1,5-AG using a pyranose oxidase assay.
Achieved over 99% glucose removal in samples with less than 25 mM glucose and above 97% efficiency in samples with 25-100 mM glucose.
Fully restored 1,5-AG signal recovery and linearity (r2 > 0.99), matching glucose-free controls.
Identical 1,5-AG standard curves in treated urine and serum confirmed elimination of matrix interference without degradation.
