It is based on oxidation bilirubin (see) nitrogenous to - that to a biliver dyne. Carefully add to a small amount of urine or other studied liquid (underlay) concentrated nitric to - that, trying to avoid mixing of liquids. In the presence of bilious pigments on border of liquids color rings are formed: green, blue, violet, red and yellow in that order, from top to down, respectively to different oxidation levels of a pigment. Emergence of a green ring is characteristic (biliverdin). In modification of this test offered by Rozenbakh (O. of Rosenbach), urine is repeatedly filtered and then in the center of the paper filter deployed on glass put a drop concentrated nitric to - you. The same painted rings are located in the same sequence from the periphery to the center. Emergence of bilirubin in urine, even in insignificant quantities, demonstrates development of mechanical or parenchymatous jaundice, infectious hepatitis, etc.
