Abstract

To the Editor: We believe that Nadel and his colleagues (Aug. 30 issue)1 are incorrect in suggesting that there is no need for amniocentesis in patients with elevated maternal serum alpha-fetoprotein levels and a normal ultrasonographic examination. Their conclusion rests on the belief that ultrasonography will virtually never miss a case of open spina bifida (detection rate virtually 100 percent) in the fetuses of women with raised maternal serum alpha-fetoprotein levels and on the assumption that there will be no false positive results. Their own estimate of the detection rate is based on their identification of 31 of 31 cases.
