Аннотация
Mass screening of maternal serum alpha-fetoprotein levels for the prenatal detection of fetuses with neural tube defects (NTDs) was introduced in Natal during 1979. From then until 31 October 1982, 12318 pregnancies were monitored and 16 fetuses with NTDs identified. A further 7 abnormal fetuses, 3 with defects other than of the neural tube, were encountered. It is shown that the screening process is reliable and that it does not generate much additional work for ultrasonographers or other laboratories. Few problems related to the management of the screening programme were met; they are discussed with particular reference to the role of ultrasonography.
