What is the meaning of urobilinogen2/eu in the urine?

Probably nothing: Two ehrlich units. The scale is 1-10. Most people have 1. If you're otherwise healthy, forget about it. I am going to assume that you are not anemic and do not have any biochemical or other evidence of liver troubles. Hemolysis from exercising can raise urobilinogen. Don't treat lab values, and remember that "normal ranges" are set so that several % of healthies fall outside at either end. Relax.

See answer: Urobilinogen is a substance formed by the breakdown of bilirubin and a small amount of urobilinogen is normally found in urine and is measured in ehrlich units (eu). Significant amounts can be a sign of liver disease (cirrhosis, hepatitis); that the flow of bile from the gallbladder is blocked; or hemolysis (excessive breakdown of red blood cells).
