PregaSight NIPT is a non-invasive prenatal test that analyzes cell-free DNA (cfDNA) from maternal blood to check for chromosomal abnormalities (aneuploidy) in the fetus. cfDNA are fragments of DNA that circulate in the mother’s bloodstream; a percentage of cfDNA originating from the fetus can be found in the pregnant mother’s blood.
cfDNA may be obtained from the mother’s blood and used to screen for certain chromosomal abnormalities as early as 10 weeks into pregnancy,
Each chromosome has segments that are unique to that chromosome, enabling scientists to link or map sequences of DNA to specific chromosomes. NIPT works by sequencing and then measuring the amount of cfDNA that comes from each chromosome. Higher or lower levels of cfDNA mapping back to a particular chromosome may indicate aneuploidy.
Results You Can Trust
Test failures in an NIPT result is essentially an inconclusive result. This can be frustrating for many families and prompts some patients to pursue invasive follow-up procedures in search of a definitive result.
PreSight NIPT helps you avoid this stress by using next generation DNA sequencing to bring you the lowest rate of test failure and results you can trust.
