Rising indirect bilirubin levels are primarily caused by hemolysis or Gilbert syndrome
the verdict
SUPPORTED
the evidence backs this
confidence 90/100
Rising indirect bilirubin levels are primarily driven by either increased bilirubin production via hemolysis or impaired conjugation due to Gilbert syndrome, supported by extensive clinical and genetic literature.
