Study Guide for Hour Test 5 Chapter 24 1. Box 24-1 lists risk factors for preterm labor. Good to review. 2. Fetal fibronectin and salivary estriol are 2 common biochemical markers used to possibly predict preterm labor. How are they used? Fetal Fibronectin – glycoproteins produced during fetal life & found in plasma. Appear in cervical canal in early & late pregnancy. Appearance between 24 & 34 weeks could predict preterm labor. Negative predictive value (who will not go into preterm labor) high. Test done during vaginal exam. If not present then 94% accurate that woman will not go into labor. If present then 46% of women may go into labor.(p771) Salivary estriol estrogen produced by fetus & is present in plasma at 9 weeks gestation. Levels increase before preterm birth. Collect salivary estriol specimens; test every 2 weeks for 10 weeks. Has high negative predictive value. Collect Mom’s saliva to measure levels of estriol (estrogen produced by the fetus). Estriol levels increase before preterm birth. Negative – 98% will not go into labor. Positive 7-25% will go into labor. 3.
