“…PAMG-1 was selected as a marker of fetal membranes rupture due to its unique characteristics (high level in the amniotic fluid, low level in blood and extremely low level in cervico-vaginal secretions when the fetal membranes are intact). The test depends on highly sensitive monoclonal antibodies that detect even a minimum amount of the PAMG-1 (5.0 ng/ml), present in cervico-vaginal secretions after the rupture of the fetal membranes [20].…”
Detection of the PAMG-1 in the vaginal fluid using AmniSure(®) test is an accurate method to diagnose rupture of the fetal membranes, with high sensitivity, specificity, negative and positive predictive values.

“…Its concentration in cervicovaginal secretion is below 0.05-0.2 ng/ml in case of intact membranes (20,28). 1000-10000-fold difference between amniotic fluid and cervicovaginal secretions puts this test forward.…”
“…La placental alpha 1-microglobulin (PAMG-1) est décrite comme une glycoprotéine placentaire dont le poids molécu-laire varie selon les auteurs de 20 ± 2 kDa à 34 kDa [55,56]. Il n'existe pas de test immunologique quantitatif permettant de la doser.…”

“…Il n'existe pas de test immunologique quantitatif permettant de la doser. Sa concentration est donc estimée comme beaucoup plus élevée dans le liquide amniotique que dans le sang maternel, les sécrétions vaginales, l'urine et le sperme selon des ratios variables selon les auteurs [55][56][57]. Un seul test immuno-chromatographique détecte PAMG-1 à un seuil annoncé de 5 ng/ml (Tableau 1) mais les anticorps qu'il utilise n'ont pas été caractérisés ni validés pour un test quantitatif, ce qui rend impossible l'établissement formel du seuil de détection.…”

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
