Urochromogen for infections

To determine the urochromogen in urine, two reactions were mainly established in clinical laboratories: diazoreaccp Ehg1i with h'a and the Weiss sample.
In the Infectious Diseases Clinic of the 2nd Moscow State University, DR and the Weiss test were conducted by me for almost three years. In view of the indications available in the literature on the existing anti-dependence in the detection of urobilinogen and urochromogen in urine, an aldehyde reaction Ehg1i with h'a to urobilinogen was also carried out at the same time. For some time, observations were carried out with the Russo reaction, but the green staining of urine, as a sign of a positive result, sometimes turned out in completely healthy people, and therefore this reaction was soon completely abandoned. With concomitant infective nephrosis and nephritis, DR was also performed with the blood serum of patients using the Heprit method described by H. Blotiier and R. Fitz.
