Hi all, this isn't related to steroids or anything but it is related to bloodwork and the liver, and I know there are some very knowledgeable people here so I hope this is ok to ask

My girlfriend recently got some bloodwork back and the dr (who I'm not too impressed with) exclaims that her liver is damaged based on the results. She's 21 years old, works out regularly, follows a decent diet, and only drinks occasionally.
The doc ordered a bunch of hepatitis tests and another liver panel, but the only thing that was out of range was AST at 95 U/L when it should be 0-45. ALT was normal at 37 U/L. Everything I can read says that usually liver damage will show high ALT and AST, and that it is usually higher numbers such as 10 times the normal range. But this is where my lack of experience shows; is AST at 95 actually high and indicative of some damage? I understand it's above normal, but the way the doctor acted made it seem more serious.

So main question really is, is AST at 95 U/L actually concerning, or just something to watch?
Additionally, they found trace amounts of Ketones in the urine, which kind of surprises me but I don't know much about how common that is. Clarity was also cloudy, as apposed to clear which got flagged by the lab too.

Thanks for any help, if anything at least any answers can hopefully give me a better understanding of the liver and what bloodwork numbers mean.
