I had a hepatobiliary scan which came back normal. My cholesterol went from 200to 170 in the year that I had the Mirena, though. I have told every doctor I have seen that I think this is too low and wierd that it would drop. Nobody agrees with me. On Thursday I'm going to see an NAET accupuncturist. Hopefully he'll be able to answer some questions for me. What test did you have for gallbladder?
