Frequently Asked Questions

Short answers to the FAQs published with this service.

• What does the ETV6-RUNX1 test measure?

It detects a specific gene fusion (t(12;21)) commonly associated with pediatric Acute Lymphoblastic Leukemia (ALL).

• Why is this test important for children with ALL?

It helps clinicians categorize risk levels and tailor the treatment intensity to achieve the best possible outcome.

• Does this test require fasting?

No, fasting is not required for this genetic molecular analysis.

• What type of sample is needed?

The analysis is typically performed using either a peripheral blood sample or a bone marrow aspirate.

• How long does it take to get the results?

Due to the complexity of molecular testing, results usually take between 7 to 10 working days.

• Does a positive result mean a poor prognosis?

Actually, the presence of the ETV6-RUNX1 fusion is generally associated with a favorable prognosis and good treatment response.
