Maternal Serum Alpha-Fetoprotein Screening
Background: The maternal serum alpha-fetoprotein test (MSAFP) was developed to screen for neural tube defects. Little is known about the adoption of the MSAFP test. This study examines the effect of provider specialty and geographic location and patient insurance status on MSAFP test use in Washington State. Methods: We conducted a retrospective cohort study of MSAFP use in low-risk obstetric p...
متن کاملMONOCLONAL ANTIBODIES TO HUMAN ALPHA-FETOPROTEIN
Alpha-fetoprotein (AFP), a serum glycoprotein belonging to the onco-developmental proteins group, serves as a marker both in cancer research and in studies concerning fetal development and fetal pathophysiology. Monoclonal anti-AFP antibodies are essential reagents in developing appropriate techniques for measurement of this protein. In this study, in order to produce anti-AFP monoclonal a...
متن کاملFirst-trimester screening for neural tube defects using alpha-fetoprotein.
OBJECTIVE To assess the potential value of maternal serum alpha-fetoprotein (AFP) at 11-13 weeks' gestation in early screening for fetal neural tube defects (NTDs). METHODS Maternal serum AFP at 11-13 weeks' gestation was measured in 32 cases of fetal NTDs, including 18 cases of acrania and 14 cases of spina bifida, and 1,500 unaffected controls. The measured serum AFP was converted into mult...
متن کاملFirst-trimester screening for trisomy 21 using alpha-fetoprotein.
OBJECTIVE To investigate the potential value of adding maternal serum alpha-fetoprotein (AFP) to free β-human chorionic gonadotropin (β-hCG) and PAPP-A and fetal nuchal translucency (NT) thickness in first-trimester screening for trisomy 21. METHODS In this case control study, serum AFP was measured in 100 trisomy 21 and 1,500 euploid pregnancies in which screening for trisomy 21 had been per...
متن کاملPrenatal fetal karyotyping and maternal serum alpha-fetoprotein screening.
Prenatal karyotyping was undertaken in 569 consecutive amniotic fluid samples where the indication for amniocentesis was two sequential raised maternal serum alpha-fetoprotein concentrations. In 475 successful cultures five chromosome abnormalities were found--four constitutional anomalies (47,XXY; 47,XYY; an inherited inv(8) (p23q11); and a de-novo translocation t(6;7) (p11;p22) and a culture-...
