Trends in timing of prenatal diagnosis and abortion for fetal chromosomal abnormalities.
Our objective was to evaluate changes in the timing of prenatal diagnosis and abortion for chromosomal abnormalities over the past 10 years. ⋯ Since 2005, the gestational ages at prenatal diagnosis and abortion for Down syndrome have declined significantly. These changes are likely attributable to improvements in early screening that leads to higher rates of chorionic villus sampling.
