What's this test for?

This test is ideal if you're being monitored for chronic lymphocytic leukemia (CLL) or a related lymphoproliferative disorder and need more information about how your condition may behave over time. It looks at specific chromosome changes in your blood cells that are linked to prognosis. It's often used after an initial CLL/SLL diagnosis to help understand disease outlook and guide monitoring decisions.

What's included in this test?

This test looks specifically for two chromosome changes in blood cells: trisomy 12 (an extra copy of chromosome 12) and deletion of part of chromosome 13 (13q14 deletion). These two findings matter because they are among the most common and clinically meaningful chromosome changes seen in CLL/SLL, and each is linked to a different expected disease course. Identifying which one (if either) is present helps put your overall condition into context.

What happens after I get my results?

Your results will be available in your account, with each finding explained in plain terms so you understand what was detected. Because this is a specialized cytogenetic test tied to an existing diagnosis, next steps typically involve discussing timing of retesting or additional monitoring based on the specific chromosome finding. A full downloadable lab report is available in your account, and you can track results over time using the trends feature. If your results indicate a finding that needs urgent attention, seek medical care promptly.

How can I naturally support my immune system during monitoring?

While chromosome findings like trisomy 12 or 13q deletion can't be changed through lifestyle, supporting your overall immune health can help you feel your best during monitoring. Eating a balanced diet, staying physically active, prioritizing sleep, and avoiding smoking or excess alcohol are all good general habits. Managing stress and staying current on recommended vaccinations can also support your body's overall resilience.

When will I get my results?

Results for this FISH test are typically ready within about 7 days of your sample being processed at the lab. This extra time is needed because the test involves specialized cytogenetic analysis of chromosomes rather than a standard blood chemistry measurement. You'll be notified as soon as your results are posted to your account.

Who should consider this test?

This test is most relevant for people who have already been diagnosed with CLL/SLL or a similar lymphoproliferative disorder and want more detail on their specific chromosome profile. It may also be considered for people with lymphocyte abnormalities found on routine bloodwork who are being evaluated further. It is not typically used as a general screening test for people without any prior findings.

What symptoms indicate I may need this test?

CLL/SLL often develops slowly and sometimes causes no noticeable symptoms at all, but some people notice swollen lymph nodes, unusual tiredness, unexplained weight loss, night sweats, or frequent infections. If you've already had blood work showing an elevated lymphocyte count, that's often the trigger for this type of follow-up chromosome testing. These symptoms alone don't confirm a diagnosis, but they're common reasons this test gets ordered.

What does it mean if trisomy 12 is detected?

A trisomy 12 finding means your blood cells have an extra copy of chromosome 12, which is a change commonly seen in CLL/SLL. This finding is generally associated with an intermediate prognosis and is sometimes linked to lymphocytes with an unusual appearance under the microscope. It's one piece of the bigger picture used to understand how your condition may behave.

What does it mean if 13q deletion is detected?

A 13q deletion means a small piece of chromosome 13 is missing from your blood cells, which is the most common chromosome change seen in CLL/SLL. This particular finding, especially when it's the only chromosome change present, is generally associated with a more favorable outlook. It's a helpful data point for understanding your specific case.

How often should I retest?

Retesting frequency for chromosome studies like this one depends on your individual situation, disease activity, and any changes in your symptoms or blood counts. Some people are retested only if their condition changes or progresses, rather than on a fixed schedule. Keeping track of your results over time in your account can help you and anyone managing your care spot meaningful changes.
