Elevated Biliruben, RBC Size Large, No Other Symptoms

W have had elevated biliruben my entire adult lift. I have also recently been told that the size of my re blood cells are very large. And, I once had elevated liver enzymes which were fully tested with no definitive results. I exercise, eat right and do not drink except maybe for a special occassion. All tests, including liver biopsy , ERCP , extensive blood work which were all negative. My question is, could these large macro red blood cells be responsible? Don t want to miss a possible lurking disease , but tired of all the testing. By the way I have no symptoms, except I do require 9-10 hours sleep each night. Thoughts?????
