What does low fetal fraction mean in prenatal testing?

Low fetal fraction refers to a lower amount of fetal DNA in the maternal blood sample, which can make some prenatal tests less reliable but does not necessarily indicate a problem with the baby.

Can low fetal fraction affect the health of my baby?

Having a low fetal fraction does not necessarily affect the health of your baby, but it may require additional testing and monitoring to ensure an accurate assessment.

What should I do if my prenatal test indicates low fetal fraction?

If you have a low fetal fraction result, it's important to follow up regularly with your healthcare provider for further testing and monitoring to ensure your baby's well-being.

Are prenatal tests less reliable with low fetal fraction?

Yes, prenatal tests such as non-invasive prenatal testing (NIPT) may be less reliable with low fetal fraction, which is why additional follow-up tests may be recommended.
