Urinary bilirubin normal means that urinary bilirubin is at a normal level in the urine. After the action of intestinal bacteria, bound bilirubin is converted into biliverdin, most of which is excreted with the feces, while only a small portion of biliverdin is absorbed by the mucous membranes of the intestines and re-enters the bloodstream. It then passes through the kidneys and is excreted in the urine, and this part of the bilirubinogen is the urinary bilirubin in question. In patients with hepatocellular jaundice or hemolytic jaundice, urobilinogen can be seen to be elevated; if patients with obstructive jaundice have negative urobilinogen, the next step should be combined with the amount of the patient’s blood bilirubin and abdominal ultrasound, etc. to find out the cause of the jaundice; normal people’s urobilinogen is usually weakly positive, and a few people are negative. When the urine bilirubin is abnormal, it is necessary to actively consult the doctor, under the guidance of the physician to carry out reasonable treatment.
