Question

in urinalysis, bilirubin in the urine may indicate disease of the multiple choice liver. pancreas. kidney. gallbladder

Explanation:

Bilirubin is a by - product of heme metabolism. The liver is responsible for processing bilirubin. When the liver is diseased, the normal metabolism and excretion of bilirubin are disrupted, which can lead to bilirubin appearing in the urine. The pancreas is mainly related to digestion and blood sugar regulation, the kidney is mainly for filtering blood and forming urine (and abnormal kidney function is more related to protein or blood in urine rather than bilirubin), and the gallbladder stores bile (gallbladder diseases usually affect bile flow but bilirubin in urine is more indicative of liver - related issues in terms of metabolic processing).

Answer:

A. liver.
