Non-invasive prenatal screening (NIPS or NIPT), is the first-line screening test globally recommended for detecting common chromosomal abnormalities & microdeletions in fetuses from the cell-free DNA present in the maternal blood sample, passed from the placenta. On average ~10% of the circulating cell-free DNA is found in the maternal blood.2 NIPT is a screening that can be done as early as at 10 weeks of gestation.

Why NIPT?
NIPT analyzes fetal chromosomal abnormalities using cell-free DNA in the mother's blood, eliminating the need for previously used invasive techniques such as Chorionic Villus sampling or amniocentesis, which carries a high risk of miscarriage. With its non-invasive nature, NIPT provides a solution and reports chromosomal abnormalities with high sensitivity.
It is important to note that NIPT is a screening test and cannot provide a final diagnosis based solely on its results. Nevertheless, NIPT demonstrates great sensitivity in detecting Down syndrome, capturing over 99% of cases3
Conditions screened for
- All autosomal chromosomal abnormalities including trisomies 13, 18, 21
- All sex chromosomal abnormalities
*This test does not reveal the sex of the fetus in accordance with PCPNDT guidelines
Clinical Utility
- NIPT can be performed as early as 10 weeks of gestation, allowing for earlier detection of chromosomal abnormalities compared to traditional screening methods.
- NIPT results can reduce anxiety and uncertainty for expectant parents by providing them with valuable information about their baby's health.
- Reduced invasive tests by 94.8% & decrease in procedure-related miscarriages by 90.8% 4
When is NIPT recommended
- NIPT is generally recommended to all pregnant woman
- If any soft marker tests (double, triple & quadruple marker) suggest for chromosomal abnormalities
- If ultrasound High NT or absent nasal bone suggests for chromosomal abnormalities
- History of a prior pregnancy with a trisomy

As of October, 2020:The American College of Obstetricians and Gynecologists (ACOG) and the Society for Maternal-Fetal Medicine (SMFM) endorse NIPT as having the highest detection rate and lowest false positive rate for the common aneuploidies regardless of maternal age or baseline risk, of all screening options.1
