The thing to remember about the Triple Screen (where they measure the fluid sack on the baby's neck, called the nuchal fold, and do a few other tests) is that it is far from 'accurate.' If 1000 women were to take the test, probably 50 would be referred for additional testing. Maybe 1% of these women would actually have a baby with down syndrome. So, if you do agree to this test, keep in mind that if it comes back 'positive' it means that your baby is probably fine anyway. Also, before you consider screenings such as these, ask yourself which of the following categories you fall into:A) You would abort a baby with down syndromeB) You wouldn't abort the baby no matter what If you fall into 'B,' ask yourself if you really want to spend your pregnancy worrying about this child - taking the test will not change the results, and if you're a worrier it could be better for the baby to not be subjected to the stress hormones your worrying would create.
