A rise in serum "direct" bilirubin would be expected in:
Absence of glucuronyl transferase as in the newborn
Decreased hepatic uptake of bilirubin (Gilbert's Disease)
- Biliary obstruction
A, B and C
A and C
B and D
- D only
All of the above
- A-C would increase the concentration of unconjugated (indirect) bilirubin.
Unconjugated bilirubin is "indirect" because it is bound to serum albumin,
and must be released by an organic solvent before it can react.
- D. In this condition bilirubin would be conjugated normally, but not excreted.
