What is Nucleus?
add
Nucleus offers a complete family planning experience, from preconception genetic testing to advanced embryo analysis and IVF care. We help you understand your own genetics and your future child’s, so you can plan with more clarity and confidence.
Where should I start?
add
It depends where you are in your journey.
If you’re interested in understanding your own health, Nucleus Health is a comprehensive genetic test that screens for over 2000 conditions you may be at risk for. These insights give you a clearer picture of your health today, and help you start more informed conversations with your doctor and other medical experts about any next steps.
If you’re just starting to think about having a child, Nucleus Preview is a simple first step and where Nucleus’ family planning services begin. It helps you and your partner understand what you might pass on, before conception.
If you’re already going through IVF, Nucleus Embryo gives you a clearer picture of your embryos so you can choose with more confidence. It’s easily integrated into any existing IVF care.
If you’re planning to do IVF and want a more supported experience, Nucleus IVF+ brings everything together in one seamless path, from clinic matching through to advanced genetic analysis and pregnancy.

How should I use this information?
add
Our genetic insights are here to give you more information, not to tell you what to do.
With Health, results typically help people make more informed lifestyle decisions, understand what to watch out for over time, and serve as a starting point for conversations with their doctor about any appropriate next steps.
With Preview, many people use their results to plan ahead for children, understand their own potential health risks, and have more informed conversations with their doctor. Some go on to conceive naturally, just with more clarity, while others explore IVF if it feels right for them.
For Embryo, the insights are used by the parents to compare embryos and make their own decisions during IVF.
How do I get my results?
add
Your results are delivered in your Nucleus account through clear, easy-to-understand reports.
You can access them anytime, and if you have questions, a genetic counselor is available to talk everything through with you.
How accurate are Nucleus’ results?
add
Nucleus’ whole-genome DNA analysis is more than 99.9% accurate. As a clinical-grade test, we’re held to the highest standards to ensure the quality of your DNA analysis.
That said, it’s important to understand how different types of genetic results work.
Some conditions are caused by a single gene. In those cases, results can be highly definitive, showing whether a specific variant is present or not.
But most health conditions and traits, like cancer risk, heart disease, or height, are influenced by many genes working together. These results are probabilistic, not certain. They reflect likelihood, not guarantees.
That’s not a limitation of Nucleus — it’s how genetics works. Environment, lifestyle, and chance also play a role. Nucleus helps you understand risk and possibilities, so you can make more informed decisions.
Why did my Nucleus results change?
add
While your DNA doesn’t change, how we analyze it can and does change your results. With more data and improved methods, your genetic insights will update over time to reflect the latest science. Our goal is to ensure your results always represent the most accurate picture of what’s known today.
Some conditions are driven by a single gene, where results are clear and unchanging. Others, like most common diseases and traits, are shaped by many genes working together. These insights are estimates of likelihood, not definitive predictions—and may evolve as the science improves.
Like a weather forecast, your results become more precise as more information and better models become available. Earlier results weren’t wrong, just less refined.
Do I need to be doing IVF to do Nucleus?
add
Not at all. Nucleus is designed for many different paths to parenthood, as well as individual health insights.
If you’re still early in your journey, we recommend starting with Nucleus Preview. It gives couples (and individuals) insight into what could be passed on to your future child, so you have more information, whatever path you take.
And if you simply want to learn more about your own health, Nucleus Health uncovers your risk for 2000+ conditions, so you can prevent future disease and live healthier, longer.
