Did you know that bits of your baby’s DNA can be found in your bloodstream? Noninvasive prenatal testing (NIPT) is a straightforward blood screening that analyzes that DNA (known as cell-free DNA, or cfDNA) to assess the risk of various genetic disorders, including Down syndrome. However, it’s important to note that while NIPT can provide valuable insights, it can also produce false positives, particularly for less common conditions, potentially leading to undue stress. Here’s what you should know to determine if these screenings are the right choice for you and your family.
What is Noninvasive Prenatal Testing (NIPT)?
NIPT is a prenatal screening method that examines DNA from your baby’s placenta found in a blood sample to evaluate whether you’re at an elevated risk of having a baby with a genetic disorder. Keep in mind, though, that while NIPT can indicate risk levels, it cannot definitively confirm the presence of a chromosomal disorder.
How is NIPT Conducted?
The process is relatively simple, involving a blood draw that can be done any time after the 10th week of pregnancy.
What Does NIPT Screen For?
This test typically screens for several common genetic conditions, such as Down syndrome, trisomy 18, and trisomy 13, among others.
Does NIPT Reveal Baby’s Gender?
Yes, NIPT can also determine the sex of your baby if you’re curious about whether you’re having a boy or a girl.
Different Types of NIPT
There are various NIPT options available, each with its own specific features and capabilities.
Timing for NIPT in Pregnancy
Generally, NIPT is performed between the 10th and 14th week of pregnancy, making it an early option for expectant parents.
How Accurate is NIPT?
While NIPT is known for its high accuracy, especially for common conditions, false positives can still occur. Therefore, confirmatory testing is usually recommended following any positive results.
Should You Consider NIPT?
Deciding whether or not to undergo NIPT is a personal choice that depends on various factors, including your medical history, risk factors, and preferences.
