An Introduction to Noninvasive Prenatal Screening (NIPS)

Did you find this information useful?

Noninvasive prenatal screening (NIPS)—also known as noninvasive prenatal testing—is a family planning option in which blood from the mother is tested to screen for a handful of chromosome conditions in the pregnancy. The blood sample will contain both free DNA from the mother and free DNA from the placenta (which in 99% of cases matches the fetal DNA). This can also predict the genetic sex of the fetus.

Some things to consider is that this test is not 100% accurate, and the sensitivity varies for each chromosome, but typically ranges from 91-99.8%. The results generally take 1 week. Additionally, there is limited availability for single-gene inherited conditions. Financially, this is typically a more affordable screening test that is usually covered by insurance, with an out of pocket cost ranging from $99-$300 in the United States. In countries with nationalized healthcare, such as the United Kingdom, NIPS may be covered.

Are you a carrier that’s utilized NIPS for family planning? We’d love to hear from you!

Master List

Check out our X-linked condition master list.

To date, there have been hundreds of X-linked conditions identified—many of them only affecting a few people around the world. While all X-linked conditions are caused by mutations on the X chromosome, each condition is different and has a unique set of symptoms.

Genetic Counselor

Find a genetic counselor for additional advice.

Genetic counselors are healthcare professionals who help individuals and families understand how genetic information impacts their lives. A genetic counselor can provide the most relevant information about each family planning option and answer your questions.
