Interpreting Test Results

fFN testing is proven to assess the risk of preterm delivery in women at risk for preterm birth — with or without symptoms — who are 22 to 35 weeks pregnant.^{1, 2}

For women at risk with symptoms of preterm labor, a positive test result may warrant consideration of increased patient surveillance and management. For women at risk but with no current symptoms of preterm labor, a positive test result may impact care decisions, such as increased intensity of prenatal observation, evaluation of other risk factors, increased patient education, and possible earlier intervention.

A negative test result helps make it possible to reassure your patient that she is highly unlikely to deliver within the next two weeks. It may also help you avoid unnecessary interventions.
