Urinary bileogen +- is normal in most cases, and in a small number of cases it is due to diseases such as hepatocellular jaundice, hemolytic disorders, and burns. A normal person has a weakly positive urine bilirubin, i.e. +-, in the urine routine. Therefore, if there are no abnormalities in other tests, especially in liver function with normal total bilirubin, direct bilirubin, and aminotransferases, it is usually normal and does not require special treatment.
A small number of patients may be due to jaundice, such as hepatocellular jaundice, hemolytic disease, or severe burns and other diseases, in the early stage of the disease urobilinogen may be weakly positive, and in the later stage of the disease, urobilinogen may gradually increase. At this time, it is necessary to improve the liver function and other related tests to confirm the diagnosis of the disease.
Patients with abnormal urobilinogen are advised to consult regular hospitals and complete relevant examinations under the guidance of physicians to clarify the cause and target treatment.
