Thanks for all your helpful replies..

Still thinking of doing the test although the doctors don't think it's that worthwhile. Not sure why not. Will have to persevere with that one.

However they said we can still do it if we want to. It has to be sent up to Sydney. We're in Melbourne.

Does anybody know how much the test costs? Esp. if you have to send it up from Melbourne? has anybody else been told it's not worthwhile?

Thanks Emilyb
