The effect of gravidity on maternal serum a-fetoprotein (AFP), unconjugated oestriol (uE,), and human chorionic gonadotrophin (hCG) levels was investigated in 27 592 women being screened for Down's syndrome. There was no difference in the median AFP level in primigravid and multigravid women, but th

We conducted a study to investigate the effect of parity on the following six serum markers used in screening for Down's syndrome, after adjusting them for ethnic group and maternal weight: alpha-fetoprotein (AFP), unconjugated oestriol (uE,), total human chorionic gonadotrophin (hCG), free a-hCG, f

High free beta human chorionic gonadotropin ( -hCG) and low alpha-fetoprotein (AFP) levels were found in 47 Asian Down's syndrome pregnancies (median values 2โ€ข79 and 0โ€ข77 MOM, respectively). At a 5 per cent false-positive rate, free -hCG alone would identify 46โ€ข8 per cent of Down's syndrome pregnanc

The effect of the choice of maternal age-specific prevalence curve on the model predicted Down syndrome detection rate was examined. All 19 published regression curves from 11 birth prevalence series in four meta-analyses were included. The detection rate for a five per cent false-positive rate was

We aimed to determine how differences in the age at which women had their pregnancies influenced the expected detection and false-positive rates of serum screening for Down 's syndrome (i) between 1970 and 1993 in England and Wales, and (ii) between regions and districts of England and Wales in 1991
