Plasma estrogens and pregnancy-associated plasma proteins: a study of their variability in late pregnancy

G M Masson et al. Obstet Gynecol. 1977 Oct.

Abstract

The plasma concentration of several estrogens (unconjugated estradiol and estriol, total estriol, and estriol sulfate) and of the placental proteins hPL and PAPP-C were measured daily for 8 days in 9 subjects. The steroids showed coefficients of variation ranging from 14 to 21%. The proteins were much less variable (PAPP-C 5% and hPL 6%).
