The most likely cause for rise in liver
enzymes of your daughter seems to be the use of pain killers.
These pain killers in general can cause liver injury
even when given in recommended dose.
One should try to avoid pain killers as far as possible.
There is no medicine which can reduce the enzyme levels in blood except removing the offending agent from your diet list.
I don't think there is any need for any test regarding the rise of liver enzymes are concerned.
