Hepatitis is an inflammation of the liver. Although there are many causes of hepatitis, the main cause in children is viral.
During the early stages of hepatitis both bilirubin and urobilin are present in the urine when tested with reagent strips. This is a useful way of confirming the diagnosis of hepatitis.
With hepatitis there is an increase in the serum concentration of the liver enzymes. The bilirubin concentration may also be raised.
