title: Maternal serum alpha-fetoprotein screening, maternal weight, and detection efficiency.
abstract: Various methods of adjusting maternal serum alpha-fetoprotein levels based on maternal weight have been recommended in order to more appropriately assign risk in maternal serum alpha-fetoprotein screening. These adjustments may, however, result in a larger proportion of pregnancies designated as having increased risk and reduction in detection accuracy.
