Between June 1994 and December 1996, we offered second-trimester serum AFP and hCG screening to pregnant women in Hon
Maternal serum alpha-fetoprotein (MSAFP), human chorionic gonadotropin (hCG), and unconjugated oestriol (UE,) are used as second-trimester screening markers for the detection of various fetal abnormalities. Previous studies have suggested that second-trimester MSAFP is consistently elevated after la
## Objective: To determine if the sex ratio (male/female) is altered in infants born to patients with low mid-trimester maternal serum human chorionic gonadotropin (mshcg). ## Study design: Between 2/1/90 and 1/3/91, 3,116 patients underwent prenatal screening using second-trimester maternal seru
