Hi and welcome,
When I was jaundiced from a severe case of acute hep b, my whole body was yellow,,,,,,it is especially noticeable in the whites of the eyes. The dr does seem to be making sure you do not have hep, so thats good that he is trying to rule that out. Sometimes this is how a dr makes a dx,,,,process of elimination. Hope your doing better soon and check back in and let us know what you find out.
