Fetal fibronectin was first reported as a possible biomarker for identifying those at risk of preterm birth back in 1991. Despite over 3 decades of ever evolving published data on FFN, underuse, misuse, and misunderstandings regarding what fetal fibronectin is and is not still persist. In the session we will review the SMFM recognized transvaginal ultrasound/FFN algorithm for preterm labor triage assessment. What is traditionally accepted as a “short cervix” on TVUS? Is it really safe to send patients home after a negative FFN result? Let’s review the data now. (Thank you Matt S. for the podcast suggestion.)
