A 5% fetal fraction in non-invasive prenatal testing is generally considered acceptable for accurate genetic screening. Fetal fraction is the proportion of fetal DNA in the mother's blood and can fluctuate due to factors like gestational age and maternal weight. Consult with your healthcare provider for personalized insights, as they can interpret results based on your specific situation.

FAQs & Answers

  1. What is fetal fraction and why is it important? Fetal fraction refers to the percentage of fetal DNA present in the mother's blood, which is crucial for accurate prenatal testing results.
  2. Can fetal fraction levels change during pregnancy? Yes, fetal fraction levels can vary based on gestational age, maternal weight, and other factors, influencing the reliability of test results.
  3. What should I do if my fetal fraction is low? If you receive a low fetal fraction result, consult your healthcare provider for further testing options and personalized advice.
  4. How is non-invasive prenatal testing performed? Non-invasive prenatal testing is done through a blood sample from the mother, which is then analyzed for fetal DNA.
