Can a yeast infection cause a positive ffn?

Yes, a yeast infection can potentially cause a positive fetal fibronectin (fFN) test result, although it is not a common cause. fFN is a protein found in the cervix that can be detected in vaginal secretions, and its presence is often associated with preterm labor. Infections, including yeast infections, inflammation, or other cervical irritations can lead to elevated levels of fFN. Therefore, while a positive fFN test may indicate the risk of preterm birth, it is essential to consider other factors and consult a healthcare provider for a comprehensive assessment.
