In a normal urinalysis, bilirubin would be:

• A. Negative
• B. Positive
• C. Trace
• D. High

Answer: (A)

Bilirubin in urine indicates a problem with liver processing or bile flow. In a healthy person, bilirubin should not appear in urine because bilirubin is produced from heme in the liver, then conjugated to a water-soluble form and excreted into the bile into the digestive tract. Only if conjugated bilirubin spills into the bloodstream or the kidneys filter it would it show up in urine. So, in a normal urinalysis, the bilirubin result is negative, meaning there is no bilirubin detectable in the urine. A positive or trace finding would suggest some liver or biliary tract issue, while a high level would be clearly abnormal.
