I just got my blood results back and everything was good but my bilirubin was high what does that mean? and what is bilirubin?

Gilbert's: Bilirubin's the green stuff in bile; your liver processes it from broken-down red blood cells. A few percent of people always have a mildly elevated indirect bilirubin from "gilbert's non-disease"; your physician knows how to detect this. If you've ever missed a few meals and turned a bit yellow, you can probably self-diagnose. Trust you're not taking meds that cause cholestasis. Your dr can tell.
