## Abstract Pregnancy can be detected early using transvaginal ultrasonography and human chorionic gonadotropin (hCG) measurements. The purpose of this study was to correlate serum hCG levels with transvaginal gestational sac measurements. The mean sac diameter (MSD) and gestational sac diameter (G
Fifty-six cases of Down syndrome were identified in a population of women who had undergone maternal serum triple marker screening [alpha-fetoprotein (AFP), human chorionic gonadotropin (hCG), and unconjugated oestriol (uE3) analyses]. These affected pregnancies represented all known cases present i
## Objective: To determine if women experiencing an unexplained elevated maternal serum alpha fetoprotein (msafp; > or =2.0 mom) or human chorionic gonadotropin (hcg; > or =2.0 mom), or low unconjugated estriol (e3; < or =0.5 mom) in one pregnancy are at increased risk for similar results in a subs
