Method Description
Glucose, in the presence of hexokinase, is converted to glucose-6-phosphate (G6P). Glucose-6-phosphate dehydrogenase (G6PDH) oxidizes G6P in the presence of nicotinamide adenine dinucleotide phosphate (NADP) to gluconate-6-phosphate and NADPH. The rate of NADPH formation is directly proportional to glucose concentration and is measured photometrically.(Package insert: Glucose reagent. Roche Diagnostics; v16.0, 02/2020)
