Welcome to the forum, Scott and Marine. Scott, it is very possible that the high dose of antibiotics you were on elevated your liver levels. Hopefully, they will have normalized at your 4-wk. retesting.
Marine, I'm very sorry to hear that you have end-stage liver disease. If you will go the folder at the top of the page, Hepatitis Resources, there is a lot of information there on the different stages of liver disease. I think you will find it helpful. Are you under the care of a hepatologist? I certainly hope so. Is there a possibility of a transplant?
