A REAGENT IS SUITABLE FOR MEASURING THE CONCENTRATION OF AN ANALYTE IN A HEMOGLOBIN-CONTAINING BIOLOGICAL FLUID, SUCH AS WHOLE BLOOD. THE REAGENT COMPRISES DEHYDROGENASE ENZYME THAT HAS SPECIFICITY FOR THE ANALYTE, NAD OR AN NAD DERIVATIVE, A TETRAZOLIUM DYE PRECURSOR, A DIAPHORASE ENZYME OR AN ANALOG THEREOF, AND A NITRITE SALT. THE REAGENT CAUSES DYE FORMATION THAT IS A MEASURE OF THE ANALYTE CONCENTRATION. THE NITRITE SALT SUPPRESSES INTERFERING DYE FORMATION CAUSED NON-ENZYMATICALLY BY THE HEMOGLOBIN. PREFERABLY, THE REAGENT IS USED IN A DRY STRIP FOR MEASURING KETONE BODIES, SUCH AS BETA-HYDROXYBUTYRATE. |
