Abstract: Ferric ion chelates are useful in analytical compositions, elements and methods for the determination of reductants, or other analytes which can produce a reductant. The ferric ion chelate is reduced to ferrous ion, which coordinates with a suitable ferrous ion coordinating ligand to form a colored complex. In particular, these compositions and elments are useful for detecting nicotinamide adenine dinucleotide, reduced form (NADH) or nicotinamide adenine dinucleotide phosphate, reduced form (NADPH), or an analyte (e.g. an enzyme) which produces NADH or NADPH in biological fluids.
