Noninvasive prenatal testing (NIPT) analyses deoxyribonucleic acid (DNA), the genetic material, in a pregnant woman's blood to estimate the risk of both chromosomal abnormalities and sex chromosome abnormalities in the developing foetus. This test screens for conditions such as Down syndrome, trisomy 18, trisomy 13, Turner syndrome, Klinefelter syndrome, Triple X syndrome, and XYY syndrome by comparing the proportion of DNA fragments from each chromosome. NIPT is typically recommended if you have a child with a chromosomal abnormality, if an ultrasound suggests potential issues, or if an earlier screening test indicates a possible problem. It can be performed from as early as 10 weeks of pregnancy through to delivery, as foetal DNA levels are usually sufficient for accurate analysis after this point. It is important to remember that while NIPT is highly accurate, it is a screening test and not diagnostic; positive results require further diagnostic testing to confirm any genetic conditions. If you live in Bangalore and your doctor has suggested NIPT, schedule an appointment today to help estimate the risk of chromosomal disorders in your foetus.

• Prerequisites: Fasting is not necessary, a blood sample is required for the NIPT for All Chromosomes test.

• Best Time to Get Tested: The test can be taken at any time unless otherwise advised by a doctor.

• When Recommended: As prescribed for prenatal genetic screening.

• Cautions: No specific precautions are required before the test.
