@phylliserin Welcome to Connect. I am really sorry to hear about your daughter. The AST and ALT results do sound high.

If a number of things were out of range I think it would be cause for concern. Is she at risk for liver problems? This link from Mayo tells causes and symptoms. I had liver disease -- cirrhosis. Mine was caused by fatty liver. Most people with fatty liver are overweight, which I was, but some people are not, it's just their diet that causes it. Other causes are mentioned in the Mayo article.
I didn't think a hospital could send a sick person home for lack of insurance. Does she have Medicaid? It does sound as if she should have some medical attention. I thought pretty much everyone was insured these days through ACA if they had no insurance other than that. I hope you are able to get her the attention she needs, I will definitely be interested in hearing what the doctor says.
