What do the results mean?

A Rapid fFN® test can help your doctor determine your risk of delivering within the next 2 weeks and guide your care accordingly, depending on whether you received a negative or positive test result.1

Negative Test Icon

Negative Result1

  • Approximately 80% of patients will get a negative result.
  • A negative result means that you have a less than 1% chance of giving birth in the next 2 weeks.
  • A negative result can help avoid unnecessary drug treatments, bed rest and hospitalizations. This knowledge can also provide peace of mind, freeing you to continue with your current activities without unnecessarily canceling or rescheduling plans.
  • The Rapid fFN test can be repeated as often as every 2 weeks to monitor your ongoing risk.

Positive Test Icon

Positive Result1

  • Approximately 20% of patients will get a positive result.
  • A positive result means your body is “leaking” fetal fibronectin, a sign that your body may be preparing to give birth.
  • A positive result does not necessarily mean you will deliver soon, but it will alert your doctor to the fact that you are at higher risk.
  • The Rapid fFN test can be repeated as often as every 2 weeks to monitor your ongoing risk.
