Why choose Unity 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 Unity Basic screen for?

  • Common trisomies: Down’s syndrome (Trisomy 21), Edwards syndrome (Trisomy 18) and Patau syndrome (Trisomy 13)
  • Sex chromosome conditions: Turner syndrome and other sex chromosome conditions
  • 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 Unity NIPT work?

UNITY 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 10 weeks)
  • Samples processed by BillionToOne in the US
  • 9 microdeletion syndromes, including: DiGeorge syndrome (22q11.2 deletion), Cri-du-chat syndrome, Prader-Willi and Angelman syndromes
  • Over 200 single-gene disorders, such as: Noonan syndrome, Skeletal dysplasias, Cornelia de Lange syndrome and Kabuki syndrome
  • Optional Fetal Sex Determination: Know your baby’s sex early, if desired.

What are the limitations of Unity NIPT?

While UNITY 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 Unity Aneuploidy Screen?

Unity 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).

Frequently
Asked Questions

What’s the difference between basic and advanced NIPT?

Basic NIPT screens for the three most common chromosomal conditions: Down’s syndrome (Trisomy 21), Edwards’ syndrome (Trisomy 18), and Patau’s syndrome (Trisomy 13). Advanced NIPT includes everything in the basic test, but can also check for sex chromosome conditions, some rare genetic deletions (called microdeletions), and can tell you the biological sex of the baby if you choose to know. At Jeen, our genetic counsellors will help you decide which version is right for you during your consultation.

Why do I need to send my scan before doing the NIPT?

We ask you to send us your scan so our medical team can confirm that you’re at least 10 weeks pregnant and that the pregnancy appears to be developing normally. This helps us ensure the test is appropriate and that the results will be accurate. It’s also important to understand that NIPT only screens for specific genetic conditions. It does not detect structural anomalies, such as heart defects or issues with organ development, which are physical rather than genetic. These types of conditions are usually picked up later in pregnancy through detailed ultrasound scans. Sending your early scan allows our doctors to check for any concerns before moving forward with the NIPT.

Can I do NIPT at home?

No - genetic testing shows your risk, not a guarantee. Some people with a genetic variant never develop the condition, while others without a variant might still be affected due to lifestyle or environmental factors.

Can NIPT tell me the sex of my baby?

Yes, NIPT can usually identify the baby’s biological sex with high accuracy, but this is completely optional. If you’d like to know, just let your genetic counsellor know during your consultation — and if you’d rather not find out, we’ll make sure it’s not included in your report.

Is NIPT covered by the NHS?

At the moment, NIPT is only offered through the NHS in certain cases — for example, if you’ve had a high-risk result from a standard screening test. At Jeen, we offer private NIPT testing with flexible options, fast results, and full clinical support, including at-home appointments and expert guidance.

How long does it take to get results?

Your results will usually be ready within 2–10 working days from the time your sample arrives at our partner lab. The exact turnaround time depends on which NIPT you’ve chosen and the location of the laboratory. We’ll keep you informed throughout the process and arrange a follow-up consultation to talk you through your results as soon as they’re ready.

Please note that delays can occur during public holidays in both the UK and the US. If your results indicate that follow-up testing is needed for your partner, we’ll act quickly to keep everything moving smoothly. Our priority is to get you the answers you need without unnecessary delays — so you can make confident, informed decisions for your pregnancy.

When can I take the NIPT and is it safe?

You can take the NIPT from 10 weeks into your pregnancy. Before booking your test with Jeen, we ask you to send us a recent pregnancy scan, such as a dating or viability scan, so our team of specialists can confirm you’re eligible to proceed.

Yes, NIPT is completely safe for both you and your baby. It’s a non-invasive blood test that only requires a small sample from your arm, and there is no physical contact with the baby. This means there is no risk of miscarriage or harm to the pregnancy, unlike some invasive procedures.

How accurate is NIPT?

NIPT is over 99% accurate at detecting Down’s syndrome and also highly reliable for Edwards’ and Patau’s syndromes. It is more accurate than standard NHS screening and produces fewer false positive results, which means fewer people are sent for unnecessary follow-up testing.

Do I need genetic counselling before NIPT?

Yes, at Jeen we believe it’s important that everyone taking NIPT has a chance to speak to a qualified genetic counsellor first. This session helps you understand what the test covers, what it doesn’t, and what the results might mean for you and your baby. It’s a space to ask any questions and make confident, informed choices.

What happens if my NIPT result is high risk?

If your result shows a high risk for a condition, we’ll arrange a follow-up session with one of our genetic counsellors to explain exactly what it means. You’ll be given the option to have a diagnostic test, such as amniocentesis or CVS, which can confirm the result. We’ll support you at every step, with clear information and no pressure.

Will NIPT detect all possible conditions?

No, NIPT screens for a specific set of genetic conditions, mostly involving extra or missing chromosomes. It won’t detect all birth defects or structural anomalies, such as heart defects or limb differences. That’s why it’s important to still attend all your routine scans and check-ups during pregnancy.
