There is something fishy about this post: the penultimate paragraph describes the blood test being discussed in the article as one that is performed so that a pregnant woman can decide whether to keep the baby. That is not a decision which frum women make, except when a pregnancy threatens her life. It leads me to question whether the poster is genuine or whether this is some sort of hoax.
I know very little about spina bifida, though I do know it is an extremely debilitating congenital disease, and so I cannot say that any advice proffered in the posting is wrong (or right, for that matter). But the casual reference to “keeping the baby” raises some questions about the source of this post.
