Dear all wise ones
Just a quick query, about the timing of AFP testing. I
was always to understand that between 16-18 weeks was optimal, and otherwise
could give (even more) unreliable results. If done at around 20 weeks,
what are the chances of this happening, and given the repercussions of further
invasive testing, what's the point if you miss the 16-18 week
period??
Looking forward to some clarification
Tania
