High bilirubin count has been associated with ME quite frequently.
I was told by my GP that it's Gilbert's Syndrome and nothing to worry about. Standard GP lack of care though, I can't see why they'd jump to that conclusion. They ignored all the other health issues and couldn't even tell me if it was conjugated or unconjugated bilirubin that was elevated because the NHS tests only show total count. I think someone on here said that they had a test that showed elevated conjugated levels, which suggests it isn't GS, but I have no idea how common that is among us.
