ABSTRACT OF THE DISCLOSURE Test compositions and test device are pro- vided which are capable of generating different hues at different analyte concentrations. The compositions are capable of generating a yellow hue in situ. Visual tests for clinically important analytes, such as glucose, are deter- mined by use of two independent catalytic systems which are reactive with reduced nicotinamide adenine dinucleotide to produce a range of hues; the particular hue produced depending on the concentration of the analyte. The invention provides a test device for the determination of analyte, e.g. glucose, in body fluid which exhibits a RAINBOW of hues, the particular final hue produced depending on the analyte concentration.
