A weakly positive urinary bilirubin is a result of a definitive urinary bilirubin test, and normal people have negative or weakly positive urinary bilirubin themselves. In addition, constipation, postprandial or alkaline urine can also cause a positive urobilinogen. Therefore, a weakly positive urine bile test in women is considered to be within the normal range and should not be a cause for concern. In clinical practice, urobilinogen is a route of excretion after the metabolism of bilirubin in the body, and another route is excretion through the intestine. This indicator is usually combined with and urobilin to identify the type of jaundice. If the urine test shows excessive urine bilirubin or more than 2+, it indicates an abnormality in the body’s bilirubin metabolism. Abnormalities in bilirubin metabolism are divided between excessive bilirubin production and abnormalities in the enzymes that metabolize bilirubin, usually involving liver, kidney and gastrointestinal tract pathologies. Urobilinogen alone cannot determine and diagnose the disease. Abnormalities in this index need to be determined by clinical symptoms, signs, liver function, virus-related tests, routine blood tests and imaging. In the case of jaundice, a negative urobilinogen and urobilin are likely to be associated with obstructive jaundice if the skin and sclera are yellow. If urobilinogen is positive, it is likely to be hepatocellular jaundice or hemolytic jaundice, and prompt diagnosis and treatment are recommended.
