The aim of this study was to evaluate the feasibility of first-trimester biochemical screening for trisomy 18, by using pregnancy-associated plasma protein A (PAPP-A) and free beta human chorionic gonadotropin (hCG) in combination with maternal age. Maternal serum levels of PAPP-A and free beta-hCG

In a study of 70 cases of trisomy 18 and 450 matched controls in the second trimester we have measured the maternal serum levels of the analytes alpha feto protein (AFP), free -human chorionic gonadotrophin (hCG) and pregnancy associated plasma protein-A (PAPP-A). We have found the median multiple o
In a study of 130 ยฎrst trimester cases of trisomy 21 and 959 controls we have shown that the median MoM for alpha-fetoprotein (AFP) is lower (0.82) and that for total human chorionic gonadotrophin (hCG) is higher (1.31) than in the control group. For AFP 15.3% of cases were below the 5th centile and
