title: An enzyme-linked immuno sorbent assay for salivary estriol during normal pregnancy.
abstract: It has been recently demonstrated that the concentration of Estriol in saliva increases in the course of pregnancy, similarly to the plasmatic concentration of unconjugated and total Estriol. As an alternative to RIA, which is an expensive method and requires a highly specialized laboratory, there is now available a competitive, sensitive and rapid enzyme-linked immuno sorbent assay (ELISA) for Estriol in saliva and plasma. Aim of this study is to compare the levels of Estriol concentration, measured by RIA and by ELISA in saliva and plasma in seven women tested every week from the 30th week to the term of pregnancy.
