ABSTRACT:
Enzymatic assays for determining glucose, creatine phosphokinase or plasma ammonia, wherein nicotinamide adenine dinucleotide is reduced or the reduced form of nicotinamide adenine dinucleotide is oxidized to nicotinamide adenine dinucleotide, are carried out in the presence of about 2 to 50 micromoles per liter of oxalic acid or oxamic acid, or salts thereof. The oxalic acid, oxamic acid and salts thereof inhibit lactic dehydrogenase which causes errors in the assays.
