AML1/ETO t(8;21) Quantitative, Real-Time PCR
Test Code14995
CPT Codes
81401
Preferred Specimen
3 mL whole blood or bone marrow collected in an EDTA (lavender-top) tube
Minimum Volume
1 mL whole blood or bone marrow • 20 uL extracted RNA
Other Acceptable Specimens
Whole blood or bone marrow collected in: Sodium heparin (green-top) or ACD-B (yellow-top) tube • 50 uL of 10 ng/uL extracted RNA submitted in a microcentrifuge tube
Instructions
Do not reject specimens, send to laboratory for screening.
Collect 3 mL of whole blood or bone marrow in an EDTA (lavender-top) tube, green-top (heparin) or yellow-top (ACD) tube. Whole blood or bone marrow is shipped at room temperature or refrigerated (cold packs). Do not freeze whole blood or bone marrow. Record the draw time and date on the tube. Information regarding draw time and date is required to ensure stability of the sample is maintained.
Extracted RNA: Only accept extracted RNA when extraction or isolation is performed in an appropriately qualified laboratory such as a CLIA-certified laboratory or a laboratory meeting equivalent requirements as determined by the CAP and/or CMS.

Negative
Clinical Significance
To detect AML1-ETO t (8;21) fusion transcript that is common in acute myeloid leukemia (AML) M2 subtype. Besides initial diagnosis and prognosis evaluation, this assay is intended to monitor the clinical course and effectiveness of therapy of Minimal Residual Disease (MRD). It may be valuable to monitor the disease trend in the same patient and predict the approaching relapse.
