NOVELTY – A process for determining the activity of the enzyme glutathione reductase in hemolysate comprises depositing oxidized glutathione, NADPH and DTNB (as oxidizing agent of reduced glutathione), all diluted in phosphate/EDTA buffer, on the surface of a lipophilic membrane located on two platinum electrodes, and monitoring the current for 3 minutes after the addition of the sample. USE – In medical equipment. The amperometric sensor may be used to evaluate oxidative stress in medicine and in sports circles. ADVANTAGE – The method gives rapid and reliable results, and may be used outside the laboratory.
