Why choose Aneuploidy Screen NIPT?
- Accurate screening: Screens for both chromosomal and genetic disorders.
- Safe and Simple: Requires only a single tube of maternal blood; no risk to you or your baby.
- Fetal Rh testing available early: This is ideal for Rh-negative mothers.
- Low Failure Rate: Low ‘no-call’ rate thanks to molecular counting technology.
- Optional Gender Reveal: Find out your baby’s sex with over 99% accuracy, if you wish.
What conditions does the aneuploidy NIPT screen for?
- Common trisomies: Down’s syndrome (Trisomy 21), Edwards' syndrome (Trisomy 18) and Patau syndrome (Trisomy 13)
- Fetal Rh testing: Fetal Rh status (for Rh-negative mothers, +£50)
- Optional Fetal Sex Determination: Know your baby’s sex early, if desired.
How does the aneuploidy NIPT work?
Aneuploidy NIPT uses a molecular counting approach to analyse DNA from your baby in your blood. This method improves accuracy and lowers the chance of inconclusive results.
- Just one blood sample from the mother (from 9 weeks)
- Samples processed by BillionToOne in the US
What are the limitations of this NIPT?
While Aneuploidy NIPT is one of the most advanced NIPTs available, it's important to understand:
- Samples processed by BillionToOne in the US, so may taken longer than UK providers.
- Positive results for rare conditions may require further testing (e.g. CVS or amniocentesis) not covered by the NHS.
Who Should Consider aneuploidy NIPT?
Aneuploidy NIPT is a strong option if you:
- Want early screening for Down’s syndrome and genetic diseases
- Are Rh-negative and want to avoid unnecessary Anti-D injections.
- Are seeking a cost-effective NIPT with excellent accuracy.
- Suitable for twin pregnancies, egg donation, and cases of vanishing twin syndrome.
The test is also suitable for twin pregnancies, egg donation, and cases of vanishing twin syndrome (aneuploidy screen only).
