Further, in the form of indican waste enters the kidney from the liver through the blood. And if at the same time, the patient there are different kinds of infections of the urinary tract, the bacteria that are separated sulfuric acid from indican, process it into indoxyl. In alkaline medium it is converted by the microflora in the two substances with red and blue hue. The mixture of these colors is the reason why urine can be painted in a blue-purple color.
