Patient sample is deposited on the slide and is evenly distributed by the spreading layer. Protein in the sample forms a complex with cupric ion and results in the dissociation of the cupric ion from the copper-azo dye complex. The decrease of the copper-azo dye complex is measured by the reflectance spectrophotometry and is proportional to the concentration of proteins in the sample.
