Can Low Fetal Fraction Result in a False Gender Prediction?

Discover how low fetal fraction levels in NIPT can lead to inaccurate gender predictions.

100 views

Yes, a low fetal fraction in non-invasive prenatal testing (NIPT) can sometimes result in a false gender prediction. This happens because there may not be enough fetal DNA in the sample to accurately determine gender. If the fetal fraction is low, consider repeating the test or consulting with your healthcare provider for alternative testing methods to ensure accurate results.

FAQs & Answers

  1. What is a low fetal fraction? A low fetal fraction refers to insufficient fetal DNA in a non-invasive prenatal test sample, which may affect the accuracy of results.
  2. How can I improve the accuracy of gender prediction tests? You can improve accuracy by ensuring enough fetal DNA is present, possibly by repeating the test or consulting your healthcare provider.
  3. Are there other methods to determine fetal gender? Yes, other methods include ultrasound and invasive tests like amniocentesis or chorionic villus sampling (CVS) for more reliable results.
  4. What should I do if I get a low fetal fraction result? Consult with your healthcare provider about possible next steps, including retesting or considering alternative testing options.
