Non Invasive Genetic Tests
NON INVASIVE GENETIC TESTS
NIPT
Non-invasive prenatal testing (NIPT) can identify a pregnancy in which the baby is likely to have a chromosome condition. These conditions are uncommon, do not usually run in the family, and can happen in any pregnancy.
NIPT can be requested from 10 weeks gestation after you’ve had an ultrasound.
What the NIPT report will include, and how you will receive your test results?
Your sample is checked to see if there is sufficient DNA to provide a reliable result. Then, for each condition included on the request form, the report will indicate whether there is a low or high probability of the condition being present.
Results will be sent to your healthcare provider in 3–5 business days.
If your report indicates a high probability of a chromosome condition being present, a CVS or amniocentesis procedure can be arranged by your doctor to obtain a definitive result.
WHAT DOES IT SCREEN FOR?
Our NIPT routinely screens for these chromosome conditions:
Down syndrome (trisomy 21)
Edwards syndrome (trisomy 18) Patau syndrome (trisomy 13)
If requested you can also screen for:
- Turner syndrome
- Klinefelter syndrome
- Other sex chromosome anomalies (Triple X syndrome and XYY syndrome)
You also have the option to determine the sex of your baby.
HOW ACCURATE IS IT?
Non-invasive prenatal testing (NIPT) is a screening test.
It is much more accurate than first-trimester blood screening and ultrasound tests. This has reduced the need for invasive tests such as chorionic villus sampling (CVS) or amniocentesis, although these will still be required to confirm a high-probability result.
NIPT screening for trisomy 21, 18 and 13 – the most common chromosome conditions – provides the highest accuracy. Screening for other syndromes or fetal sex is reasonably reliable; however, it is not as accurate as the screening for trisomy 21, 18 and 13.
