I know soooo many people who had false positives on their AFP tests, it's not even funny (including myself). I am surprised that they want to do an amnio. Are you at high risk for downs/advanced maternal age etc.? Kinda surprising. Actually know one person with a child who has downs who tested negative. I think that test is one of the WORST. anyway, good luck with whatever you do. Ask lots of questions, research. It is scary, tho.
