Which bilirubin pattern is most consistent with increased red cell destruction when hepatic conjugation is intact?
1Predominant increase in unconjugated bilirubin✓ 정답
2Isolated increase in urine conjugated bilirubin with no serum change
3Complete absence of bilirubin production
4Predominant increase in delta bilirubin only
해설
Breakdown of heme increases bilirubin production before hepatic conjugation, so hemolysis commonly produces a predominant unconjugated, or indirect, bilirubin increase.
