Patient: I recently went to have blood drawn to check for a thyroid disorder. My blood work came back fine except my bilirubin level is 2.0. I did eat/drink before my blood test. They doctor said i did not have to fast for it. My question is, would wating before alter my level and make it out of the normal range? Also, i cant see a gi doctor until 3 weeks, is this level harmful? Thank you!
