What's this test for?

This test is ideal if you're already diagnosed with chronic lymphocytic leukemia or small lymphocytic lymphoma (CLL/SLL) and need more information about how the disease may behave. It's typically used to check for a specific genetic change called del(11q), which can affect prognosis and guide treatment planning. This test is not a general cancer screening test — it's a specialized follow-up test used alongside other clinical information.

What's included in this test?

This test uses a lab technique called FISH (fluorescence in situ hybridization) to look specifically for a missing piece of chromosome 11 that contains the ATM gene. Detecting this deletion matters because it's one of the most common genetic changes seen in CLL/SLL and it's linked to a more aggressive disease pattern. Knowing whether this deletion is present helps put your specific case into a clearer prognostic and treatment context.

What happens after I get my results?

Your results will show up in your account along with an explanation of what a positive or negative finding for the ATM gene deletion means. Because this is a specialized genetic test tied to an existing CLL/SLL diagnosis, next steps usually involve discussing findings with your care team rather than a simple lifestyle change, and results should always be viewed alongside your full clinical picture. A downloadable lab report is available in your account for your records, and you can revisit or share it anytime. If you're tracking this alongside other tests, the trends feature lets you see your testing history over time.

Who should consider this test?

This test is meant for people who already have a confirmed or suspected diagnosis of CLL/SLL and want additional genetic information about their condition. It's often ordered as part of a broader work-up alongside other FISH panels looking at chromosomes 13, 12, and 17. It is not intended for general population cancer screening or for people without a CLL/SLL diagnosis.

What symptoms indicate I may need this test?

CLL/SLL can cause swollen lymph nodes, unexplained fatigue, frequent infections, unintended weight loss, or night sweats. If you've already been told you have CLL/SLL and your lymph nodes are notably enlarged, that can be a sign your care team may want to check for the 11q deletion specifically. This test is generally ordered after a CLL/SLL diagnosis is already established, not to figure out if you have the disease in the first place.

When will I get my results?

Results are generally ready in about 7 days from when your sample is processed by the lab. This turnaround reflects the specialized nature of FISH genetic testing, which takes longer than routine blood work. You'll be notified as soon as your results are available in your account.

What does it mean if the ATM deletion (11q) is detected?

A positive result means the lab found that a portion of chromosome 11, including the ATM gene, is missing in your leukemia cells. This finding is associated with a more aggressive form of CLL/SLL and noticeably enlarged lymph nodes, and it's one of the pieces of information used to think through prognosis and treatment options. It does not tell you everything about your outlook — it's one input among several genetic and clinical factors.

What does a negative result mean?

A negative result means the lab did not find the 11q22.3 deletion in the sample tested. This does not rule out other genetic changes linked to CLL/SLL, such as deletions of chromosome 13, 12, or 17, which are often tested for separately. Your full genetic profile, put together from multiple tests, gives the clearest picture of your specific disease pattern.

How often should I retest?

This is generally not a test you repeat routinely — it's typically done once at diagnosis or at key decision points in your CLL/SLL care, such as before starting a new treatment or if the disease appears to be changing. Because genetic profiles of CLL/SLL cells can shift over time or with treatment, retesting may be considered later if your clinical picture changes significantly. There is no fixed interval for this test the way there is for routine blood work.

What should I do if my results show the ATM deletion?

If your results are positive for this deletion, the most useful next step is to have this information reviewed alongside your other CLL/SLL test results, since it's meant to be interpreted as part of a bigger clinical picture rather than on its own. Keep a copy of your report for your records and bring it to your next care appointment. If you notice new or worsening symptoms like rapidly swelling lymph nodes, fevers, or drenching night sweats, seek medical care promptly.
