What's this test for?

This test is ideal if you're being evaluated for a possible lymphoma, especially one affecting the stomach, lungs, or other mucosal tissue. It looks for specific genetic changes that help distinguish MALT lymphoma from other low-grade lymphomas. This information can be important for understanding your diagnosis and planning next steps.

What's included in this test?

This test uses a technique called FISH (fluorescence in situ hybridization) to look for a specific gene rearrangement called MALT1, and if found, automatically checks for a related fusion between the BIRC3 (API2) and MALT1 genes. These genetic changes are closely linked to a type of lymphoma that starts in mucosal tissue, so finding them can help clarify a diagnosis. Detecting this fusion is also useful because it's linked to how certain gastric lymphomas respond to treatment.

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 this specific genetic marker. Because this is a specialized diagnostic test, next steps often include additional genetic testing or clinical follow-up depending on what is found. You can download the standard lab report directly from your account at any time. If you retest in the future, you'll also be able to track results over time using the trends feature.

How can I naturally support my immune system during evaluation?

While no lifestyle change can affect a genetic test result, supporting your overall immune health can be helpful during a diagnostic workup. Eating a balanced diet with plenty of fruits, vegetables, and lean protein, staying hydrated, getting regular sleep, and managing stress can all support your body's general resilience. Avoiding smoking and limiting alcohol are also commonly recommended during any period of medical evaluation.

When will I get my results?

Results for this test are typically ready within about 7 days of your sample being processed at the lab. FISH testing involves specialized lab procedures, which is why it takes a bit longer than routine blood work. You'll be notified as soon as your results are ready to view in your account.

Who should consider this test?

This test is generally considered for people who have findings suggestive of a marginal zone or MALT lymphoma, often after a biopsy of affected tissue such as the stomach or lungs. It's also relevant for people already diagnosed with a lymphoma who need further genetic characterization to guide treatment decisions. This is a specialized test, so it's typically used as part of a broader diagnostic workup rather than as a first step.

What symptoms might lead someone to need this type of testing?

People are often referred for this kind of genetic testing after experiencing persistent stomach discomfort, unexplained weight loss, chronic cough or breathing issues, or swelling in the lymph nodes. These symptoms alone don't point to lymphoma specifically, but when combined with imaging or biopsy findings, this test can help clarify what's going on at the genetic level. If you're having ongoing, unexplained symptoms like these, it's worth discussing testing options with wherever you're receiving care.

What does a positive result for the MALT1 or BIRC3/MALT1 fusion mean?

A positive result means the specific genetic rearrangement was found in the tested tissue, which supports a diagnosis of MALT lymphoma. In gastric cases specifically, this finding has also been linked to a lower chance of the lymphoma resolving with standard H. pylori treatment alone. This kind of result is usually reviewed alongside biopsy findings and imaging to build a complete clinical picture.

What does a negative result mean?

A negative result means this particular gene rearrangement was not detected in the sample tested. This doesn't rule out lymphoma altogether, since MALT lymphomas can involve other genetic changes, such as IGH/MALT1, IGH/BCL10, or IGH/FOXP1 rearrangements, that this specific test doesn't check for. Additional testing may be needed to get a fuller genetic picture if lymphoma is still suspected.

What should I do if my results come back abnormal?

If your result is positive for this genetic rearrangement, it's a good idea to discuss the finding along with your other test results, such as biopsy and imaging, to understand your full diagnostic picture. Because this result can influence treatment decisions, especially for gastric lymphoma, timely follow-up is recommended. Keeping a copy of your lab report handy for any future appointments or additional testing is also a smart step.
