Yes, My Doctor's Assistant Gave Me Some Preliminary Blood Results.

Yes, my doctor's assistant gave me some preliminary blood results. When talking about my kidney (I only have one) she said my AST levels were 9 and I should be at 15-37 is a normal range. This isn't making sense to me. I thought AST was for your liver function? Also, the levels aren't making sense either. Perhaps I misunderstood her. Anyway, can you confirm if AST levels are done for your kidney or liver?
Thank you,
