Historical document, translated for reference. It reflects medical knowledge of the 1920s–30s and is not medical advice.
Summary
Bilirubinuria is the excretion of bilirubin in the urine, where it is not normally present, occurring when blood bilirubin levels rise. This condition leads to dark beer-colored urine with yellow-tinted foam upon shaking, most prominently observed in mechanical jaundice. Detection of bilirubin in the urine is classically performed using Gmelin's test.
Encyclopedia entry (1928–1936)
BILIRUBINURIA, the excretion of bilirubin in the urine, where it is not normally present. When the bilirubin content in the blood increases, it can be excreted through the kidneys; urine containing bilirubin has a more intensely colored appearance resembling dark beer, and the foam formed upon shaking the urine is colored yellow. The most pronounced development of bilirubinuria is observed in mechanical types of jaundice. To detect bilirubin in the urine, Gmelin's test is used (see Gmelin's test).
