Common questions

FAQs

How is Preview different from what's offered in clinics?

add

Preview gives you a broader look at what your future child could inherit, screening 2,000+ diseases, conditions, and traits. It’s directly available to prospective parents, but it’s also a clinical-grade genetic test that’s already used in many IVF clinics too.

Most traditional preconception genetic tests (often called carrier screening) focus on a defined set of serious single-gene conditions. That matters, but it doesn’t reflect the full range of questions many parents have today.

Preview includes that rare disease screening and expands beyond it. It estimates likelihood for common health risks like cancer, diabetes, and heart disease, along with likely traits such as eye color, height, and IQ.

How can Preview tell me about things like diabetes or cancer?

add

Preview looks at your DNA to understand genetic patterns linked to common conditions like diabetes, heart disease, and many cancers.

Unlike rare diseases that are caused by a single gene, most common health conditions are influenced by many genes working together. So instead of searching for one rare mutation, Preview looks at lots of small genetic factors that, together, shape likelihood.

How can Preview estimate traits like IQ and height?

add

Traits like height, IQ, and eye color aren’t determined by a single gene. They’re shaped by many genes working together. Preview analyzes how those genes combine in you and your partner to estimate what’s more or less likely in a future child.

Do I need a partner to do Preview?

add

It helps, but you don’t have to. You can do Preview on your own to understand what you might pass on. If a partner tests too (even later on), you can easily pair your results and see the combined genetic picture, which is the most complete view.

If you’re testing on your own, you can purchase a Nucleus Health kit and still unlock your Preview insights:

Do I have to be doing IVF to do Preview?

add

Not at all. Many couples do Preview as their first step in family planning, whether IVF is already in the cards for them, or they’re hoping to conceive naturally. The goal is to get more information at the earliest point, so you can take steps to reduce risk and make decisions that support your future child’s long-term health.

Don't let your family history
define your family's future.
