title: [Improved diagnosis fetal erythroblastosis due to Rh factors by combination of spectrophotometry (delta E 450) and a modified amniotic fluid ratio].
abstract: 154 tests of amniotic fluid of 70 rh-sensitized women, won by transabdominal amniocentesis in the time between the 28th and 39th week of gestation were analysed. Besides experiential carried out spectrophotometric after Liley (estimation of delta E 450) liquor ratio were scrutinized concerning its value of statement for antenatal diagnosis in 2 variations (original liquor ratio and liquor ratio II). An equivalent pertinent judgment of delta E450 and Original liquor ratio was won. The best results were obtained with liquor ratio II and the combination of this method with delta E450. For further improvement of diagnostic reliability 2 methods of amniotic fluid analysis should be combined.
