What's this test for?

This test is ideal if you're experiencing unexplained nerve pain, numbness, heart problems, or you have a family history of a condition called hereditary transthyretin amyloidosis. It looks at your genes to see if you carry a change that can cause protein buildup in your nerves, heart, or other organs over time. Many people take this test because a relative was diagnosed with a TTR-related condition and they want to understand their own risk.

What's included in this test?

This test looks specifically at the TTR gene to check for sequence variants, which are small changes in your DNA that can affect how a protein called transthyretin behaves in your body. Finding a variant matters because certain changes are linked to a condition where this protein misfolds and builds up in tissues like the heart and nerves, so knowing your gene status can help you and your family plan ahead.

What happens after I get my results?

Your results will show up in your online account with a clear explanation of what a normal versus a variant result means for the TTR gene. If a variant is found, practical next steps include sharing the report with family members who may also want to get tested and watching for early symptoms like tingling, numbness, or shortness of breath so you can act quickly if they appear. You can download a standard lab report anytime from your account, and since this is a one-time genetic result, there's no need for retesting, though you can keep it saved and track any related follow-up tests over time using the trends feature.

How can I naturally support healthy nerve and heart function?

While you can't change your genes, you can support your nerves and heart with simple daily habits. Eating a balanced diet rich in omega-3 fats, staying physically active, limiting alcohol, and managing blood pressure all help protect nerve and heart tissue. Regular check-ins on symptoms like numbness, fatigue, or swelling can also help you catch changes early.

When will I get my results?

Results are typically ready within about 7 days of your sample being processed at the lab. You'll get a notification once your report is available in your account, so there's no need to call and check. Because this is a detailed genetic test, it takes a bit longer than routine blood work.

Who should consider this test?

This test is a good fit if you have a close relative diagnosed with hereditary transthyretin amyloidosis or a related nerve or heart condition. It's also worth considering if you have unexplained symptoms like numbness, tingling, irregular heartbeat, or heart failure with no clear cause. People planning a family who want to understand inherited health risks may also find this test useful.

What symptoms indicate I may need this test?

Common signs linked to TTR-related conditions include numbness or tingling in the hands and feet, unexplained weight loss, carpal tunnel syndrome in both hands, irregular heartbeat, and shortness of breath or swelling from heart problems. These symptoms often develop slowly over years, so many people don't connect them until a family member is diagnosed. If you notice a combination of these along with a family history, this test can help clarify the cause.

What does a positive variant result mean?

A positive result means you carry a change in the TTR gene that's associated with hereditary transthyretin amyloidosis, a condition where a protein builds up in tissues like your heart and nerves. It doesn't mean you currently have symptoms or will definitely develop the condition, but it does mean you should watch closely for early signs and consider testing close family members. Simple steps like staying active, eating heart-healthy foods, and getting periodic symptom check-ins can help you stay ahead of any changes.

What causes TTR gene variants?

TTR gene variants are inherited, meaning they're passed down from a parent to a child, and they've been present since birth. They aren't caused by lifestyle, diet, or environment. If a variant runs in your family, each child of a carrier has roughly a 50% chance of inheriting it.

What should I do if my results show a variant?

If your results show a TTR variant, start by keeping a record of any new symptoms like numbness, fatigue, or heart palpitations so you can act early if they appear. Share your results with close biological relatives, since they may want to get tested too. Seek medical care promptly if you develop concerning symptoms like chest pain, severe swelling, or difficulty breathing.
