ABSTRACT:
A method of determining lactate dehydrogenase activity in biological fluids comprising reacting a biological fluid sample with a coupled enzyme series in an oxygenated aqueous solution containing lactate, nicotinamide adenine dinucleotide and an electron transfer agent, and measuring the uptake of oxygen by the oxidation of the resulting NADH with an oxygen-sensing electrode.
