Urine bilirubin is weakly positive, which is a normal manifestation. Urine bilogen originates from human blood, and the bilirubin formed after destruction, which is circulated through the liver and intestines, absorbed into body fluids by a small part of the intestines and excreted through urine, shows suspicious positive, which is a normal manifestation and does not require any treatment or further related tests. If the urinary bilirubinogen is negative, or if the urinary bile element shows a strong positive result, further tests, such as liver function and bilirubin levels, are needed to find out if there is hepatocellular jaundice or if there is obstructive jaundice. When suffering from obstructive jaundice disease, the urinary bilirubinogen may be negative. When hepatocellular jaundice is present, urobilinogen may be a strong positive result, along with elevated urinary bilirubin levels, with generalized yellowing of the skin and sclera. Patients need further liver ultrasound and biliary ultrasound to clarify the presence of diseases of the hepatobiliary system.
