Down's syndrome screening in multiple pregnancies using alpha‐fetoprotein and free beta hCG

1 Jul 1994

Abstract excerpt

Second-trimester distributions of the free beta human chorionic gonadotrophin (hCG) and alpha-fetoprotein (AFP) levels in 420 twin and 19 triplet pregnancies were measured and compared with the distributions in 6661 singleton pregnancies. On average, the levels of both analytes were twice as high and over three times as high in triplets. Eight sets of twins discordant for Down's syndrome showed elevated levels of...
