1. What is the main flex of NIPT when screening for Down Syndrome compared to traditional first-trimester methods?
It tests the amniotic fluid directly It boasts a massive 99% detection accuracy with way fewer false positives It eliminates the need for ultrasounds completely
2. How does NIPT actually pull this genetic data without physically touching the fetus or placenta?
Using high-frequency ultrasound waves By analyzing cell-free fetal DNA circulating in the mother's bloodstream By swabbing the cervix
3. What is the earliest gestational age you can confidently order an NIPT for accurate results?
8 weeks 10 weeks 15 weeks
4. Besides Down Syndrome (Trisomy 21), what other major chromosomal conditions does NIPT routinely screen for?
Cystic Fibrosis and SMA Trisomy 18, Trisomy 13, and sex chromosome aneuploidies Spina bifida and cardiac defects
