Question: 1 / 400

What does a fetal fibronectin (fFN) test result indicate with 99% probability?

Birth within 24 hours

Birth within 2 weeks

A fetal fibronectin (fFN) test is primarily used to assess the risk of preterm labor. When the test result suggests a 99% probability, it indicates a high certainty regarding the outcome it predicts. A negative fFN result is associated with a very high likelihood of no imminent labor, meaning the patient is not likely to deliver within the following two weeks. This is why a result indicating a probability of 99% leads to the understanding that the individual will not give birth in that timeframe.

While a positive fFN may suggest there is a risk for preterm labor within the next two weeks, the specific scenario of a 99% probability relates directly to the likelihood of not experiencing imminent labor. Therefore, the correct interpretation of the test result aligns with the prediction of stability regarding labor within that two-week window.
