متن کاملThe prevalence of adverse obstetric outcomes follow of an abnormal maternal serum AFP and NTDs screen positive group
Introduction: Prenatal maternal serum AFP screening tests have some inherent false positive and false negative results. For NTDs Screening test (FTS) false positive rate (FPR) is about 1% and false negative rate (FNR) is 20%. A false positive result encourages by Anomaly scan and invasive diagnostic procedures (that poses lots of stress on women, too), while a false negative result lead to a N...
متن کاملThe role of maternal serum alpha-fetoprotein, human chorionic gonadotrophin and oestriol in the antenatal screening of Down's syndrome.
The use of maternal age alone to identify pregnant mothers at risk of a fetus with Down's syndrome has recently been supplemented by maternal serum screening using biochemical markers such as alpha-protein, human chorionic gonadotrophin and oestriol. These tests have been reported to increase the sensitivity of antenatal detection of such fetuses from 35% to 67% with a false positive rate of 5%...
متن کاملPhysical and psychomotor development of 1799 children born after second trimester amniocentesis for maternal serum positive triple test screening and normal prenatal karyotype.
In a previous retrospective study on the physical and psychomotor development of 868 children born after positive maternal serum triple test screening with normal prenatal karyotype, we found an increased incidence of complex multiple congenital anomalies syndromes (1.95%). In the present retrospective study, we collected data on 1799 children born after a pregnancy with a positive maternal ser...
متن کاملMaternal serum PAPP-A and free β-hCG at 12, 22 and 32 weeks' gestation in screening for pre-eclampsia.
OBJECTIVE To examine the distribution of maternal serum pregnancy-associated plasma protein-A (PAPP-A) and free β-human chorionic gonadotropin (β-hCG) at 12, 22 and 32 weeks' gestation in singleton pregnancies which develop pre-eclampsia (PE) and examine the performance of these biomarkers in screening for PE. METHODS Serum PAPP-A and free β-hCG were measured in 94 989 cases at 11-13 weeks, 7...
متن کاملNo. 261-Prenatal Screening for Fetal Aneuploidy in Singleton Pregnancies.
OBJECTIVE To develop a Canadian consensus document on maternal screening for fetal aneuploidy (e.g., Down syndrome and trisomy 18) in singleton pregnancies. OPTIONS Pregnancy screening for fetal aneuploidy started in the mid 1960s, using maternal age as the screening test. New developments in maternal serum and ultrasound screening have made it possible to offer all pregnant patients a non-in...
