NIPT - Non-Invasive Prenatal Screening Test
The Non-Invasive Prenatal Test (NIPT) is a highly accurate blood test available from 10 weeks of pregnancy. It offers expectant parents valuable insights into their baby’s health by screening for the most common chromosomal conditions.
How Does NIPT Work?
A small sample of your blood is drawn and analyzed for genetic material (DNA) from both you and your baby. Normally, human cells have 23 pairs of chromosomes (46 in total). The NIPT meticulously examines DNA fragments to detect any instances where there is an atypical amount of genetic information for a given chromosome. This provides accurate screening for common chromosomal changes observed in pregnancy, including:
- Trisomy 21 (Down syndrome)
- Trisomy 18 (Edwards syndrome)
- Trisomy 13 (Patau syndrome)
- Sex chromosome changes
For even more comprehensive insights, Nandini IVF offers genome-wide screening for chromosomal changes that may impact the placenta and overall pregnancy health.
While NIPT is the most accurate screening test available during pregnancy, it’s crucial to understand that it’s a screening test, not a diagnostic test. Any identified changes require follow-up counselling and diagnostic testing to confirm the findings. Our experienced team of genetic counsellors and ultrasound specialists are readily available to guide you through your next steps
What Support is Available?
All patients who undergo the NIPT receive complimentary access to experienced prenatal genetic counsellors. They are there to answer your questions, explain your results, and provide compassionate guidance.
Understanding Common Chromosomal Conditions Trisomy 21 (Down Syndrome)
Trisomy 21, or Down syndrome, occurs when there is an extra copy of chromosome 21 in all or most cells. It is the most prevalent chromosomal condition. Pregnancies affected by Down syndrome have an increased risk of miscarriage. Individuals with Down syndrome experience varying degrees of intellectual disability and distinctive physical features and may have developmental delays. While certain aspects of life, such as healthcare and education, might present more challenges, people with Down syndrome are increasingly integrated into mainstream schooling and are achieving greater independence and workplace involvement.
Trisomy 18 (Edwards Syndrome)
Trisomy 18, or Edwards syndrome, results from an extra copy of chromosome 18 in all or most cells. This condition is associated with a high rate of miscarriage, and sadly, babies born with Edwards syndrome typically have a significantly shortened life expectancy. They may present with structural heart and kidney problems, intellectual disability, and developmental delay.
Trisomy 13 (Patau Syndrome)
Trisomy 13, or Patau syndrome, occurs when all or most cells have an extra copy of chromosome 13. Similar to Edwards syndrome, Trisomy 13 leads to a high rate of miscarriage. Tragically, babies born with Patau syndrome rarely survive beyond the first few weeks of life, often facing severe difficulties with feeding and breathing, as well as significant heart and brain abnormalities.
