AFP article
"Physician-researchers at Boston's Brigham and Women's Hospital, after studying 87,584 pregnancies, reported that an elevated AFP [alpha-feto-protein] level in conjunction with a normal ultrasound scan implies a less than 0.1 percent chance that the baby will have one of the four most common birth defects. In light of the finding that amniocentesis itself carries a 0.5 to 1.5 percent chance of terminating a pregnancy (Robin J.R. Blatt, Prenatal Tests), the researchers have concluded that "many women may choose not to have an amniocentesis when informed that the risk of pregnancy loss is substantially greater than the likelihood of finding an anomaly". (New England Journal of Medicine 323, No. 9, Aug 30, 1990)"
