What's this test for?

This test is ideal if you're being evaluated for a blood or bone marrow disorder like myelodysplastic syndrome (MDS) or acute myeloid leukemia (AML). It looks for a specific chromosome change (loss of chromosome 7 or part of it) that helps confirm a diagnosis and understand how serious the condition may be. It's typically used alongside other blood work and clinical findings, not as a first-line screening test.

What's included in this test?

This is a single, specific test rather than a panel of multiple biomarkers. It uses a lab method called FISH (fluorescence in situ hybridization) to look directly at chromosome 7 in your cells, checking for a missing copy (monosomy 7) or a deletion in part of it (7q31). This matters because these specific chromosome changes are strongly linked to certain bone marrow and blood cancers and affect how they're staged.

What happens after I get my results?

Your results will be available in your account, with an explanation of what the finding means and how it compares to a normal (negative) result. Because this test relates to a serious diagnosis, an abnormal result should prompt prompt follow-up testing and care, so seek medical care quickly if you receive a positive finding. You can download the full lab report from your account at any time, and use the trends feature to keep a record of this and any future related testing over time.

Who should consider this test?

This test is typically considered by people who already have signs of a blood disorder, such as abnormal blood counts, unusual bruising, fatigue, or frequent infections, and are being worked up for MDS or AML. It's also used to monitor a known diagnosis or to help understand the outlook after a diagnosis has already been made. It is not a general wellness or screening test for the public.

When will I get my results?

Results for this test typically take about 7 days to process, since FISH testing requires specialized lab analysis of chromosome samples. You'll be notified as soon as your results are ready to view in your account. If more time is needed due to sample complexity, this is normal for cytogenetic testing.

What symptoms indicate I may need this test?

Symptoms that might lead to this kind of testing include ongoing fatigue, unexplained bruising or bleeding, frequent infections, or abnormal results on a routine blood count. These symptoms alone don't point specifically to a chromosome 7 abnormality, but they're common reasons someone gets referred for a deeper cytogenetic workup. If you're experiencing these symptoms, this test is usually ordered as part of a broader evaluation, not on its own.

What is monosomy 7 and why does it matter?

Monosomy 7 means a cell is missing one full copy of chromosome 7, which normally comes in a pair. This is one of the more common chromosome changes found in myeloid blood disorders like MDS and AML, and its presence usually signals a more serious or higher-risk form of the disease. Knowing whether this change is present helps guide how a diagnosis is understood and tracked over time.

What does a positive result mean?

A positive result means the lab found monosomy 7 or a 7q31 deletion in your sample, which is associated with MDS or AML and generally points to a higher-risk category of disease. This is important information but is just one piece of a larger clinical picture that includes your blood counts, symptoms, and other test results. A positive finding should lead to prompt follow-up care and further evaluation.

How often should I retest?

Retesting frequency depends on your specific clinical situation, such as whether you're newly diagnosed, in treatment, or monitoring for changes over time. Some people are retested at set intervals to track how a condition is responding to treatment, while others may only need this test once for diagnostic purposes. Use the trends feature in your account to keep track of results if retesting is part of your monitoring plan.

What should I do if my results are abnormal?

If your result comes back positive for monosomy 7 or the 7q31 deletion, treat this as important information that requires timely follow-up, especially if you're already experiencing symptoms like fatigue or abnormal blood counts. Keep a copy of your downloadable lab report for your records and any future appointments. Seek medical care promptly to discuss what this finding means for your specific situation and next steps.
