You might want to do some research on Gilbert's Syndrome. The main sympton is elevated bilirubin levels, sometimes mild jaundice -- it is not a serious condition.
Here's an excerpt from Mayo Clinic online:
Gilbert (zheel-BAYR) syndrome is a common, mild liver disorder in which the liver doesn't properly process a substance called bilirubin. Bilirubin is produced by the breakdown of red blood cells. Also known as constitutional hepatic dysfunction, unconjugated benign bilirubinemia and familial nonhemolytic jaundice, Gilbert syndrome typically doesn't require treatment or pose serious complications.
In fact, Gilbert syndrome is usually not considered a disease because of its benign nature. You most often find out you have the disorder by accident, when you have a blood test that shows elevated bilirubin levels."

Your wife should probably be checked for hepatitis as well, so it can be ruled out...
Good luck! Hope everything turns out ok...
Elevated bilirubin is a symptom of hepatitis. A level over 2 or so usually means
a person will be jaundiced. Does your wife have yellow skin or eyes?
And does she have a risk factor for hepatitis, such as blood transfusion, before 1992, or
intravenous drug use in her past?
