title: [Antenatal diagnosis. 601 chromosome examinations (author's transl)].
abstract: 601 antenatal chromosome tests were carried out by culturing amniotic liquor. The fetal caryotype was abnormal in 18 cases (3.1 per cent). Most of the examinations were carried out because of advanced maternal age and they gave rise to the diagnosis of 15 abnormalities (3.3 per cent). It should be possible to carry out this kind of screening of patients over the age of 38.
