I also have Gilbert's syndrome - Bilirubin level above the norm. When first diagnosed I asked "and?...." "so yr Bili level is above average" "and?" said I, "well it's just that you have a higher level than normal" said he" "So?" said I. And we went round this loop until I finally asked if this would ever have any effect on my life or chosen career and the answer was no. Off thread, but there is a ref to Bilirubin aka Billy Rubin in the book of "Silence of the Lambs"
ps bilirubin is involved in giving colour to yr pooh!!
