Maybe they test for it so they can find out if you have the disease early on and can be fully informed before continuing TTC?
My bad, I'm sorry! Note to self from now on...

Teddy, thank you for your huge array of information! I haven't got a chance to go over it all at the moment (just got the net back on at the new place and thought I'd pop on for a quick sec!) but as soon as I do I'll make a more detailed reply. Thank you tho!!! x
