What's this test for?

This test is ideal if you're being evaluated for a blood or bone marrow disorder linked to abnormal cell growth. It looks for a specific genetic change involving the FGFR1 gene that is associated with certain rare blood cancers. This test is typically used alongside other clinical findings to help characterize what's going on at the genetic level.

What's included in this test?

This test uses a technique called FISH (fluorescence in situ hybridization) to look at your chromosomes directly under specialized detection methods. It checks specifically for rearrangements involving the FGFR1 gene, which can fuse with other genes and switch on abnormal growth signals in cells. Detecting this fusion helps identify a specific pattern seen in certain blood and bone marrow conditions.

What happens after I get my results?

Your results will be available in your account, with an explanation of what the finding means. If the translocation is detected, the report will explain the result clearly so you understand what it indicates; if it's not detected, that will also be explained in plain terms. This test is typically a one-time diagnostic test rather than something you retest routinely, though your results can still be tracked over time in your account if repeat testing is ever needed. A standard lab report is also available to download at any time.

How can I naturally support healthy blood cell production?

While this test looks at a specific genetic change that lifestyle changes can't reverse, supporting overall health can help your body function well. Eating a balanced diet with adequate iron, B12, and folate supports normal blood cell production. Staying hydrated, avoiding smoking, and getting regular movement also support overall wellness. These steps don't treat the genetic finding itself but are good general health habits.

When will I get my results?

Results for this test are typically ready within about 7 days after your sample is processed at the lab. Because this is a specialized genetic test, it takes longer than routine blood work to complete. You'll be notified as soon as your results are posted to your account.

Who should consider this test?

This test is generally considered for people who have unusual findings on a blood count or bone marrow evaluation that suggest a growth-related blood disorder. It's also used when there's a need to look more closely at chromosome changes involving the FGFR1 gene. This is typically ordered as part of a broader diagnostic workup rather than as a routine screening test.

What symptoms indicate I may need this test?

Symptoms that might prompt this kind of testing include unexplained fatigue, easy bruising or bleeding, frequent infections, unexplained weight loss, or swollen lymph nodes. An abnormal blood cell count found on routine bloodwork can also lead to this type of specialized follow-up testing. These symptoms alone don't confirm anything specific, but they're often the reason more detailed genetic testing is considered.

What is the FGFR1 gene and why does it matter?

FGFR1 is a gene that gives instructions for a protein involved in cell growth and division. When FGFR1 fuses with certain other genes due to a chromosome rearrangement, it can become permanently switched on, causing cells to grow and divide when they shouldn't. This type of abnormal signal is linked to specific rare blood and bone marrow conditions.

What does a positive result mean?

A positive result means the lab detected the FGFR1 gene rearrangement in your sample. This finding is used alongside your other test results and clinical picture to understand what type of condition may be present. It doesn't tell you everything on its own, but it's an important piece of the overall diagnostic picture.

What should I do if my results show the rearrangement is present?

If your results show this genetic change, it's important to follow up promptly given the specialized nature of this finding. Bring your report to your next care visit so it can be considered alongside your other test results and symptoms. If you're experiencing severe symptoms like significant fatigue, unexplained bleeding, or fever, seek medical care right away rather than waiting.
