Urine test urobilinogen +1 What's going on?

Urine routine examination, urobilinogen a (+, suggesting that there may be hepatocellular jaundice, need to further examine liver function, liver virology and liver B ultrasound to further exclude. When there is hepatocellular jaundice, you can show elevated levels of bilirubin in the blood, part of bilirubin from the urine, part of bilirubin from the intestinal tract, from the intestinal tract can be converted to urobilinogen. Most of it is converted into fecal bilinogen through fecal excretion, and some of it is reabsorbed into the liver through the portal vein and recombined to form bilirubin into the intestinal tract. However, during this process, a small amount of urobilinogen is filtered through glomerulus or through renal tubules to form urobilinogen, which will show an elevated level of urobilinogen. Urobilinogen will also become urobilin when contacted with air. In urine routine examination, it may also be accompanied by a slightly higher level of bilirubin in urine.
