question: Hello, I am a 29 yr old woman, got bloodwork done for strep and it showed liver abnormality i guess. they sent me for further blood work a week later and my alt was 140, ast was 64 and ggt was 82. Everything else was normal range. Whats the most likely cause or most common cause for this? I am not a drinker, never done drugs.. etc etc. I have had kids and had cholestasis of pregnancy throughout my 3 pregnancies but that was a few years ago....
