Non-Invasive Prenatal Screening (NIPS)

Find out the chance of your pregnancy being affected by a chromosome condition

Early, non-invasive insights into your pregnancy
As early as week 10, find out if your baby has an increased chance for chromosome conditions like Down syndrome.
Watch this short video to learn more about NIPS.

Normal developmental processes cause small pieces of DNA from your baby’s placenta to enter your bloodstream. Non-invasive prenatal screening (NIPS) analyzes these fragments, called cell-free DNA.

All that is needed to perform NIPS is a simple blood draw from your arm, causing no increased risk to you or your pregnancy. Results are available in approximately 1 week.

What’s the difference between a screening test and a diagnostic test?

When it comes to tests you might have during pregnancy, it’s important to understand that some are screening tests, while others are diagnostic tests.

Screening tests can tell you whether there is an increased or decreased chance of something happening. Diagnostic tests, on the other hand, give definitive answers about the presence or absence of a certain condition.

Screening tests and diagnostic tests provide different types of information.

Non-invasive prenatal screening (NIPS) is a screening test. Because of this, in the unlikely event you get a positive result, you will be offered a diagnostic test to confirm or rule out a diagnosis.

There are two types of diagnostic tests available for chromosome conditions. Chorionic villus sampling (CVS) can be done during the first trimester and amniocentesis can be done during the second trimester.

Both CVS and amniocentesis are invasive procedures that carry small risks, including miscarriage. That is why many women opt to first undergo a screening test to see if there is an increased chance of a condition which can then be confirmed with a diagnostic test.
