The GOPOD Regent may be light yellow or light pink in colour when freshly prepared. It will develop a stronger pink colour over 2-3 months at 4°C. The colour will not affect your results. When using various lots of GOPOD reagent, the absorbance values for the glucose standards should be the same or very similar when you zero the spectrophotometer against the reagent blank.
