Can a parent refuse treatment for their children in the hospital? (URGENT) HELP!

[Uan]

There is a lady in Nashville, Tn who has a 13 year old daughter who is in Vanderbilt children hospital. The little girl went into the hospital for seizures, they admitted her and started running test and giving her medication since being in the hospital her condition has gotten  worst. The hospitals says that the little girl has a rare" dis-ease", they did not give a name for this rare dis-ease but they want to keep running test and basically treat this little girl as a lab experiment. When the mother wanted to discharge her daughter the hospital called chidren's services on her. Is there anyone who can give some advice on how the mother should handle the situation?

I would get court order and argue religious reasons. Not sure if would work due to agreement on admission.
