Mariam,
I think you should discontinue exjade for a while,my daughter's SGPT reached 231 and her doctor has already discontinued her exjade,we'll wait for a week,repeat the test and then we'll see what are the levels,700 is too much and Aysam is so young,can't you change your doctor while you are in Australia? One of our members Smurfette is also in Australia and she is managing herself very well,you can PM her and ask her if she can guide you to a better doctor.
Good luck,
Zaini.
