Norwitz ER, Robinson JN, Challis JRG
Title: The control of labor
Source: N Engl J Med. 1999;341(9):660-66

Title: Use of fetal fibronectin in clinical practice
Source: Obstet Gynecol Surv. 1997;52(4 Suppl):S1-12
Summary: "In low-risk asymptomatic patients, the positive predictive value is lower (15-25 percent), but is important because women in this group, destined to deliver as a consequence of preterm labor, may have no other symptoms to forebode preterm delivery."
NIH Study CJ, Kuczynski E

Title: The preterm prediction study: recurrence risk of spontaneous preterm birth. NICHD Maternal Fetal Medicine Units Network
Source: Am J Obstet Gynecol. 1998;178(5):1035-40
Summary: "The study predicted that the recurrence risk of spontaneous preterm birth is increased by twofold to fourfold in women with a positive compared with a negative fetal fibronectin test result, and it increases as cervical length shortens in both fetal fibronectin-positive and fetal fibronectin-negative women."

Summary: "The study concluded that a positive cervical or vaginal fibronectin test result predicts subsequent positive fetal fibronectin positivity and subsequent preterm birth. The greater the percent of positive results, the higher is the risk of spontaneous preterm birth. After a positive test result, two negative results are required before the risk of spontaneous preterm birth returns to baseline."
