An investigation was performed evaluating persistence of fetal fibronectin in cervicovaginal secretions after sexual intercourse. Fetal fibronectin samples were positive at 12 to 24 hours, 24 to 48 hours, and 48 to 72 hours after coitus in 22.2%, 11.8%, and 5.6% of samples, respectively. A history of vaginal intercourse should be obtained before sampling for fetal fibronectin to eliminate this potential source of false-positive fibronectin test.
开展了一项关于性交后宫颈阴道分泌物中胎儿纤连蛋白持续性的调查。在性交后12至24小时、24至48小时和48至72小时的胎儿纤连蛋白样本中，分别有22.2%、11.8%和5.6%呈阳性。在采集胎儿纤连蛋白样本之前，应了解阴道性交史，以消除这种导致纤连蛋白检测出现假阳性的潜在来源。
