Low maternal serum levels of pregnancy associated plasma protein A (PAPP‐A) in the first trimester in association with abnormal fetal karyotype

1 Apr 1993

Abstract excerpt

OBJECTIVE: To assess the relation between maternal serum pregnancy associated plasma protein A (PAPP-A) in the first trimester and the outcome of pregnancy by karyotype. DESIGN: A retrospective study of PAPP-A levels in blood samples collected prior to chorionic villus sampling. SETTING: Milan, Italy. SUBJECTS: Five hundred twenty-two women aged 20 to 47, at 7 to 11 weeks gestation, prior to undergoing chorionic...
