What Does a Normal Urobilinogen Level of 3.4 Mean?

1. A urobilinogen level of 3.4 umol/L indicates a normal result in the urobilinogen test.

2. Urobilinogen is a product of bilirubin broken down by bacteria. A urobilinogen level of 3.4 umol/L suggests that the test result is generally normal. The normal range for adult males is typically 0.30-3.55 umol/L, and for adult females, it is 0-3.64 umol/L.

3. Urobilinogen is a substance produced when bilirubin is broken down by bacteria in the intestines. Part of the urobilinogen is reabsorbed by the intestines, converted into bilirubin by the liver, and then re-enters the intestines. A small portion of urobilinogen is filtered by the glomerulus and excreted through the urine via the renal tubules.

4. If abnormal urobilinogen levels are found in the urine, immediate liver function tests, liver and kidney color Doppler ultrasonography, and urine routine tests should be conducted to further diagnose the disease. If the test finds a urobilinogen level of 3.4 umol/L, it indicates a normal result and there is no need for concern.
