What does +- urinary bilinogen mean?

  The urine triple bile test includes three tests: urinary bilirubin qualitative test, urinary bilirubin definitive test and urinary bilirubin qualitative test. The urinary bilirubinogen determinant (UBG) can be used for the differential diagnosis of hemolytic jaundice, hepatocellular jaundice and obstructive jaundice. In normal subjects, the urinary bilirubinogen is generally weakly positive. Increased urinary bilirubinogen is most often seen in hemolytic jaundice and hepatocellular jaundice. Urobilinogen is an indicator in routine urinalysis. Urobilinogen +-, which indicates suspicious or weakly positive urinary urobilinogen, is seen in normal urine. Any factor that affects the metabolism of bilirubin in the body and increases the amount of conjugated bilirubin in the blood can raise urinary bilirubinogen. For example, hemolytic jaundice and other hemolytic diseases, autoimmune hemolytic anemia, liver and biliary tract diseases, viral hepatitis, liver abscess, biliary cirrhosis, and primary liver cancer can increase urinary urobilinogen levels.
