It's interesting that a lot of people have mentioned CF (cystic fibrosis) as one of the conditions tested for. CF is tested for in all states of Australia, but there is more debate about its inclusion OS, especially in the States.

I understand that they are offering more carrier screening (before you get pregnant) for CF in Victoria and possibly interstate. Has anybody been offered carrier screening for CF, and have you had it done? I was recently offered it, and took the offer up but i haven't heard of anybody else having it done.

1/25 white people will be a carrier for CF.

1/625 couples will both be carriers for CF (1/25 x 1/25 = 1/625)

Each couple has a 1/4 chance of having a baby with CF, so 1/2500 babies will be born with CF
(1/625 x 1/4 = 1/2500)

Some of the other conditions tested for, like PKU, are even more important to get the early diagnosis because there are no symptoms of the condition until irreparable damage has occurred.
