You've got questions, we've got answers...

What is the Hazel™ Non-Invasive Prenatal Screen?

The Hazel™ Non-Invasive Prenatal Screen (NIPS) is a blood-based screening test for pregnant parents. It screens for three of the most common chromosomal conditions seen in pregnancy - Down syndrome (trisomy 21), Edwards syndrome (trisomy 18) and Patau syndrome (trisomy 13). Hazel™ can be performed as early as nine-week gestation through a simple blood collection which can be completed at home.

How early can I take the Hazel™ Non-Invasive Prenatal Screen?

The Hazel™ Non-Invasive Prenatal Screen can be performed as early as 9 weeks into your pregnancy, counting from the first day of your last menstrual period. 

Can I order the Hazel™ Non-Invasive Prenatal Screen for myself, or does it need to be ordered by my doctor? 

You can order the Hazel™ Non-Invasive Prenatal Screen directly through our website. Because Hazel™ is a medical screen, a physician will review your order  before we ship a kit to you. Alternatively, your prenatal care provider can order Hazel™ on your behalf directly from Juno.  If they do not have an account at Juno they can contact us directly at support@junodx.com

When will I receive my results?

Once the JunoDx lab receives a Hazel™ sample, results are typically available within 2-4 business days. At that time, you’ll get an email notification and be able to view your results in your myJuno portal. 

How accurate are the results of the Hazel™ Non-invasive Prenatal Screen?

The Juno Hazel™ Non-Invasive Prenatal Screen has a >99% accuracy when patients follow our easy, video-assisted process for collection. 

Do I really have to do the video-assisted collection?

Yes, our video-assisted collection process is critical in ensuring you receive the most accurate result possible. We’ve found Juno lab results to be >99% accurate when patients complete the quick and easy video walk-through with our expert Customer Care team.

Do you have a guarantee? What happens if I receive an inaccurate result?

While the Hazel™ Non-Invasive Prenatal Screen is highly accurate, false-positive or false-negative results are possible with any screening test. Please contact our Customer Care team if you’re concerned about a potential discrepancy in your Hazel™ NIPS results.

Is the Hazel™ Non-Invasive Prenatal Screen safe?

Because Hazel™ is a non-invasive screen that analyzes a maternal blood sample, it’s safe for you and your baby!  

How does the Hazel™ Non-Invasive Prenatal Screen work?

Hazel™ uses next-generation sequencing technology to read the code of millions of short DNA segments found in your blood. These fragments come mostly from you, but also from your baby’s placenta. Hazel™ checks the amount of DNA in your sample. If Hazel™ finds more or less  DNA in your sample than what we’d expect, this difference in DNA is most likely from your pregnancy – not from you. 

Who is the team behind Juno?

The Juno team includes leading scientists, genetic counselors, medical doctors, and engineers. Before Juno, our founding team worked together at Sequenom, Inc., pioneering the development and commercialization of the first cell-free DNA-based NIPS in the United States.

How do I learn more about the science behind the test?

As the pioneers behind the first non-invasive prenatal screen in the United States, our founding team has written extensively about cell-free DNA and non-invasive prenatal screening. Here are the links to just a few of these articles.
