What is non invasive prenatal test?
Non-invasive prenatal screening looks at fragments of DNA (cell-free DNA or cfDNA) in your blood during pregnancy to provide accurate information about the likelihood of chromosomal conditions that can impact your baby’s health.
This test can be performed as early as 10 weeks of pregnancy and screens for the most common chromosomal conditions such as trisomy 21 (Down syndrome), trisomy 18, trisomy 13, sex chromosome aneuploidies (SCA) and 22q11.2 microdeletion.
Who should consider non-invasive prenatal test?
- Women of advanced maternal age
- Family history of chromosomal errors
- Early ultrasound scan shows abnormalities
- Abnormal first trimester screening
Please note that the test is also suitable for women who are carrying more than one baby (twins), women who have used an egg donor or embryos, or have received a bone marrow transplant. The test is unsuitable for women whose pregnancy has resulted from a consanguineous relationship.
