Liver tests, bilirubin and a blood count in the blood are the next step.

Urobilinogen breaks down in light and air, so a sample left standing reads falsely low. Some antibiotics lower it, and some medicines and dyes can colour the pad.

Questions
Is a urobilinogen of 4.0 mg/dL normal?
A urine urobilinogen of 4.0 mg/dL is well above the normal 0.2 to 1.0 mg/dL. The usual range is 0.2 to 1.0 mg/dL (the same as EU/dL).
Worked out by LifeFrom from the usual urinalysis ranges (American Family Physician), and not yet reviewed by a clinician. For your own understanding: only a lab test, read by your clinician, diagnoses anything.
