What's this test for?

This test is ideal if you're aware of a specific cystic fibrosis (CF) gene variant that runs in your family and it falls in a region of the CFTR gene not covered by standard carrier screening panels. It helps if you have a relative already diagnosed with a rare CFTR mutation and you want to know if you carry that exact same change. This is not a general screening test, it's a targeted check for a known familial variant.

What happens after I get my results?

Your results will be available in your account, with an explanation of what a positive or negative finding means for that specific variant. If the variant is found, next steps typically include sharing this information with family members who may also want to be tested and discussing family planning options. A downloadable lab report is available in your account for your records, and you can revisit your result anytime through the trends feature. Because this is a one-time genetic result rather than a value that fluctuates, retesting is generally not needed unless a new variant needs to be checked.

Who should consider this test?

This test is meant for people who already know that a specific, rare CFTR gene variant exists in their family, usually because a relative has been diagnosed with CF or identified as a carrier through more detailed genetic workup. It's especially relevant for partners of known carriers who are planning a pregnancy. If you don't know your family's specific variant, a broader CF carrier screening panel is a better starting point.

What symptoms indicate I may need this test?
This test isn't based on your own symptoms, it's based on family history. If a close relative has been diagnosed with cystic fibrosis or found to carry an unusual CFTR variant not included in standard panels, that's the main reason to consider this test. It's also useful if you or a partner are planning a pregnancy and want to rule out carrying the same familial variant.
How can I naturally support healthy lung and digestive function?
While carrying a CF gene variant itself can't be changed through lifestyle, supporting overall lung and digestive health is always a good idea. Staying active, avoiding smoke exposure, eating a balanced diet, and staying well hydrated all support healthy lungs and digestion. These habits are helpful for general wellness but don't affect your genetic carrier status.
What is a CFTR gene variant and why does it matter?
The CFTR gene provides instructions for a protein that controls the movement of salt and water in and out of cells, especially in the lungs and digestive system. Certain changes, or variants, in this gene can cause cystic fibrosis when a person inherits a variant from both parents. Knowing whether you carry a specific familial variant helps you understand your own carrier status and can inform decisions about family planning.
What does a positive result mean?
A positive result means the test found the specific CFTR variant that runs in your family in your DNA, making you a carrier of that particular gene change. Carrying one copy of a CF variant usually does not cause symptoms since CF typically requires a variant from both parents. If your partner is also a carrier of a CF-related variant, discussing family planning options is a reasonable next step.
What does a negative result mean?
A negative result means this specific familial variant was not found in your DNA sample. This lowers the chance that you are a carrier for this particular CF-related change, though it does not rule out other unrelated genetic variants outside the scope of this targeted test. If you have further questions about CF risk, a broader carrier screening panel may still be worth considering.
What should I do if my results are abnormal?
If your result shows you carry the familial CFTR variant, consider sharing this information with close relatives since they may carry it too and might want to get tested. If you're planning a pregnancy, it's helpful to know whether your partner has also been tested for this or other CF-related variants. Genetic counseling resources, such as contacting a genetics information line, can help you understand what the result means for your family planning.
How often should I retest?
This is a one-time genetic test, since your CFTR variant status does not change over time. There's generally no need to retest for the same variant once you have a clear result. Retesting would only be relevant if a different, new familial variant needs to be checked in the future.

What this means

A negative result means the specific CFTR variant found in your family member was not detected in your sample. This significantly lowers the chance that you carry this particular familial variant, though it does not rule out other CF-related gene changes not covered by this test. Discuss this result in the context of your family's genetic history.

* Regular blood test results (e.g., CBC) typically start arriving the next business day after sample collection. More advanced tests may take longer due to complexity.
