Ggt 171 alt 51 not abusing alcohol or drugs not taking pain relief just finished co amoxiclav 625 mg three times daily for 7 days?

I'm not impressed: About 1 person in 1000 has an autosomal dominant gene that keeps the GGT high all the time. It's not specific as a 'drunk screen' if the person's baseline value isn't known.

Maybe "hepatitis": Hepatitis is defined as inflammation of liver cells, as is indicated by elevation in serum transaminases (ast, alt, ggt). Hepatitis can be caused by a variety of issues (infectious, ischemic, metabolic, toxic, infiltrative, alcohol-related, drugs, etc.). Ggt is not however specific to just the liver--so, what tests have been done ; what has been ruled out?
