Routine cervical length and fetal fibronectin screening in asymptomatic twin pregnancies: is there clinical benefit?

By on October 23, 2015

At MFMA and Carnegie Imaging, we utilize cervical length and fetal fibronectin (fFN) screening in patients at increased risk for preterm birth, such as twin pregnancies.  Our twin calculator ( allows patients and doctors to predict the risk of preterm birth in twins using these simple, low-risk tests.  In this 2013 publication in the Journal of Maternal-Fetal and Neonatal Medicine, we demonstrated that the use of these tests was associated with improved administration and timing of antenatal corticosteroids, which is the single most important intervention in improving outcomes among preterm babies.
