What's this test for?

This test is ideal if you're experiencing early movement, mood, or memory changes that could point to Huntington disease, or if you have a parent, sibling, or other close relative diagnosed with the condition. It helps confirm a diagnosis in someone already showing symptoms, or provides a pre-symptomatic answer for people with a family history who want to know their genetic status before symptoms start. It's also useful for family planning if you want to understand the chance of passing the condition to children.

What's included in this test?

This test looks specifically at the HTT gene to count the number of CAG repeats, since an abnormally high repeat count is what causes Huntington disease. Analyzing this single gene region matters because it's the definitive genetic marker used to confirm diagnosis, predict future risk in people without symptoms yet, and estimate the chance of passing the gene to children.

What happens after I get my results?

Your results will be posted securely in your account, along with an explanation of what the specific finding means for the CAG repeat range measured. Depending on the result, next steps might include genetic counseling resources, discussing family planning options, or simply keeping the report on file for future reference since this is a one-time genetic result rather than something that changes over time. You can download the full lab report directly from your account at any time, and because Huntington disease status doesn't fluctuate, this isn't a test you'll need to track with the trends feature like a typical biomarker.

How can I naturally support brain and nervous system health?

While no lifestyle change can alter your genetic result, supporting overall brain health can help with quality of life. Regular aerobic exercise, a diet rich in omega-3 fatty acids and antioxidants, good sleep habits, and mentally stimulating activities are all associated with better cognitive resilience. Staying socially connected and managing stress through activities like meditation can also support long-term brain and mood health.

When will I get my results?

Results are typically ready within about 7 days of your sample being processed at the lab. Because this is a specialized genetic analysis, it takes a bit longer than routine blood work, so plan for about a week's turnaround before your report appears in your account.

Who should consider this test?

This test is a good fit for people who already show possible symptoms of Huntington disease, such as unusual jerky movements, personality changes, or difficulty with coordination and memory. It's equally relevant for people who are symptom-free but have a parent or sibling diagnosed with Huntington disease and want to know their own genetic status. Couples planning a family where one partner has a family history of the condition may also consider this test to understand potential risk to future children.

What symptoms indicate I may need this test?

Common early signs include involuntary jerky movements (called chorea), clumsiness or balance problems, slurred speech, mood swings, irritability, or depression, and difficulty concentrating or remembering things. If these symptoms are appearing in someone with a known family history of Huntington disease, that combination is a strong reason to consider testing. Symptoms usually appear gradually and can be mistaken for other conditions, which is why genetic confirmation is so useful.

What is Huntington disease and why does it matter?

Huntington disease is an inherited condition caused by an expanded repeat in the HTT gene that leads to progressive damage in the brain over time, affecting movement, thinking, and emotional control. It matters because it's passed from parent to child, so knowing your status can guide personal health decisions and family planning. Because it's a genetic condition, the test result is definitive and doesn't change with lifestyle or time, unlike many other health markers.

What does a high (expanded) repeat result mean?

An expanded CAG repeat count above the normal range confirms a genetic diagnosis of Huntington disease, and the size of the expansion can give a rough idea of when symptoms might appear, with larger expansions generally associated with earlier onset. If you're not yet showing symptoms, this result means you carry the gene and will very likely develop the condition at some point in life, though exact timing varies a lot between individuals. This information can be a lot to process, so many people find it helpful to talk with a genetic counselor and connect with support communities.

How often should I retest?

This is not a test you need to repeat. Because Huntington disease is caused by a fixed genetic change present from birth, your CAG repeat count will not change over time, so a single accurate result is considered final and definitive.
