What Does This Test Measure?

NIPT uses a blood sample from you to detect tiny fragments of your baby’s DNA floating in your blood. It analyzes these fragments to estimate the likelihood of chromosomal abnormalities, such as Down syndrome, trisomy 13, or trisomy 18. The test does not provide a definitive diagnosis but helps guide further evaluation if needed.

How Is This Test Performed?

A small blood sample is taken from your arm. The DNA from your baby is extracted and analyzed using advanced laboratory techniques to generate risk estimates for chromosomal conditions.

When Is This Test Used?

NIPT is typically offered between 10 and 22 weeks of pregnancy as part of prenatal screening, especially for women at higher risk or as a voluntary option for all pregnant individuals.

What Are the Possible Results?

Results may include a low risk of chromosomal abnormalities, an increased risk prompting further testing (such as amniocentesis or chorionic villus sampling), or an indeterminate result requiring additional evaluation.

Reference range

Frequently asked questions

Why might I need this test?
Your healthcare provider may recommend NIPT if you are at higher risk for chromosomal conditions (e.g., due to age, family history, or previous pregnancy outcomes) or as a voluntary screening option.
What does an ‘increased risk’ result mean?
An increased risk does not mean your baby definitely has a condition. It signals that further diagnostic testing (like amniocentesis) may be recommended to get a definitive answer.
Can I get this test if I’m not at higher risk?
Yes, NIPT is often offered as a voluntary screening test for all pregnant individuals, regardless of risk factors, to provide peace of mind and early guidance.
