My lab results indicated that my bilirubin level is 1.78 mg/dl and i had my hepatitis test and it was negative. could it be jaundice or gilberts syndr?

Find cause: If your eyes are yellow and your bilirubin is up then you are jaundiced. Folks with gilbert's non-disease get a bit jaundiced if they miss a few meals; if indirect bilirubin has been up before & all else is okay you've probably got gilbert's. Trust you are not hemolyzing (cbc & smear normal) and nothing else points to illness.

Gilbert syndrome: Individuals with gilbert syndrome have a limited capability to conjugate bilirubin and presents with an intermittent jaundice.
