What's this test for?

This test is ideal if you're experiencing symptoms that suggest cystic fibrosis but earlier targeted genetic tests didn't find both gene changes needed to confirm it. It's also useful if you or a family member has signs of CF and you want a thorough, first-line look at the entire CF gene rather than a limited screening. This is not the right test for routine pregnancy-related carrier screening — a different expanded panel is better suited for that purpose.

What's included in this test?

This test reads through the entire CF gene rather than just checking a handful of common spots, so it can catch rare or unusual changes that simpler tests miss. This matters because CF can be caused by hundreds of different possible gene changes, and a full sequencing approach gives you a much more complete picture when initial testing wasn't conclusive.

What happens after I get my results?

Your results will appear securely in your account, with a plain-language explanation of what your specific findings mean. Because this is a detailed gene sequencing test, next steps depend on what's found — if a disease-causing variant is identified, retesting isn't necessary, but you may want to discuss family planning or symptom management options based on the report. You can download the full lab report from your account at any time, and if you test other family members later, you can track and compare results over time using the trends feature.

Who should consider this test?

This test is a good fit for people who have CF symptoms but whose earlier genetic screening didn't identify two disease-causing variants. It's also useful for those who want a thorough first-line genetic look without starting with a smaller targeted panel. It is not intended as a routine carrier screen for couples planning a pregnancy — a different expanded carrier panel is recommended for that situation.

When will I get my results?

Results are typically ready within about 7 days of your sample being processed at the lab. Gene sequencing takes a bit longer than basic blood work because the entire gene is analyzed in detail. You'll get a notification as soon as your report is available in your account.

What symptoms indicate I may need this test?

Common signs that point toward CF include frequent lung infections, persistent cough, thick mucus, poor growth or weight gain (especially in children), and digestive issues like greasy stools. If you've had inconclusive results from a smaller CF panel but still have these symptoms, full gene sequencing can help find rarer variants. A family history of CF alongside any of these symptoms is another reason to consider this test.

What is cystic fibrosis and why does it matter?

Cystic fibrosis is a genetic condition that causes the body to produce unusually thick, sticky mucus, which can clog the lungs and block the pancreas from working properly. It's caused by changes in a single gene, and there are hundreds of different possible variants that can lead to it. Identifying the exact variant matters because it can guide symptom management and helps you understand the chance of passing it on to children.

What causes a positive or inconclusive CF gene result?

A positive result means a disease-causing change was found in one or both copies of the CF gene, which can happen randomly or be inherited from a parent who carries the variant. An inconclusive result can happen when a variant of uncertain significance is found — meaning scientists aren't yet sure if it causes disease. In these cases, testing other family members can sometimes help clarify what a specific variant means for your health.

What should I do if my results show a CF variant?

If your report identifies a disease-causing variant, it's a good idea to share the results with close family members, since they may want to get tested too. Simple next steps include staying on top of respiratory health with good hydration, airway clearance techniques, and monitoring for lung infections early. If you're planning a family, understanding your specific variant can help you think through reproductive options.

How often should I retest?

Genetic results don't change over time, so there's no need to repeat this exact test once you have a clear result. However, if your initial report comes back inconclusive, or if new variants are discovered by science in the future, you may want to consider updated testing. Family members can also get their own one-time test to see if they carry the same variant.
