The first manifestation in cases of conjugated hyperbilirubinemia is commonly a brownish discoloration of the urine. Although scleral icterus may also be present, this typically reflects the unconjugated fraction of bilirubin that binds tissues much more avidly.

If sufficient unconjugated bilirubin is present, the skin, sclerae, and mucous membranes take on a yellow color, although this may be difficult to detect if the tissues are pigmented naturally.

Depending on the underlying illness, stigmata of chronic liver disease may or may not be present.
