First-Line Prenatal Screening Test Globally recommended for detecting Fetal Abnormalities
WHAT IS NIPT?
Non Invasive prenatal screening (NIPT), is the first-line screening test globally recommended for detecting common chromosomal abnormalities in fetus such as trisomy 21 (Down syndrome), trisomy 18 (Edwards syndrome), and trisomy 13 (Patau syndrome)from the cell-free DNA present in the maternal blood sample, passed from placenta. On an average ~10% of the circulating cell free DNA is found in the maternal blood.
NIPT is a screening can be done as early as at 10 weeks of gestation.
NIPT test screen for genetic abnormalities in the fetus
Autosomal Chromosome Aneuploidies
Sex Chromosome Aneuploidies
Microdeletions
When is NIPT recommended
- Advanced maternal age(<30)
- Any Abnormalities found in NT scan, Ultrasound scan, Nasal bone absent
- Any Abnormal biochemical marker results(AFP, bHCG, PAPP-A)
- Family history of genetic disorders
- History of a prior pregnancy with a trisomy
- Couple with history of infertility or pregnancy loss(miscarriages or stillbirths)
NIPT Advantages
Identify risk for chromosomal abnormalities - trisomy 13, 18, 21 and X-Linked Anomalies and microdeletions
Early intervention of child’s genetic health - as early as the 8 -10th week of gestation
Non-invasive, safe and accurate - this technique allows for a broad implementation of first-trimester prenatal screening.
Reduced invasive tests by 94.8% & decreased procedure-related miscarriages by 90.8%
High detection rate & Low failure rate
>99% sensitivity and specificity
*This test does not reveal sex of the foetus in accordance with PCPNDT guidelines
Test sample requirements
4-5 ml Maternal blood in streck tube
How Does NIPT Work?
Sample Collection
Your Doctor places a request for the test. The sample is tested for the susceptibility.
Lab Processing
The sample processed on Illumina Global Screening Array Bead chip
Data Analysis
Your genetic sequence is subjected to extensive Cytogenetic analysis to extract your health information.
Report Generation
Our team generates a comprehensive report based on genetic findings, reviews the report, and shares it with your doctor via email.
