Previously this has been interpreted as a flaw in the scoring system. However, it may well be that in some twin pairs the gestational ages are slightly different...
متن کاملPrecision in estimating gestational age and its influence on sensitivity of alphafetoprotein screening.
The interpretation of maternal serum alpha-fetoprotein (AFP) concentrations in relation to fetal neural tube defects depends on accurate assessment of the gestational age. In a quadruple-blind study three antenatal methods of assessment--namely, menstrual dates, clinical examination, and ultrasound scanning--were correlated with postnatal assessment using the Dubowitz scoring system. The best a...
متن کاملCost-effectiveness of estimating gestational age by ultrasonography in Down syndrome screening.
OBJECTIVE To quantify the financial benefits of using ultrasound estimation of gestational age in maternal serum screening for Down syndrome. METHODS Maternal age-specific sensitivity and false-positive rates for Down syndrome were derived for the triple test (alpha-fetoprotein, hCG, and unconjugated estriol) using gestational age based on ultrasound dating and also time from the last menstru...
