BCR-ABL1 Gene Rearrangement, Quantitative, PCR
MessageCollect 6 mL of whole blood or 3 mL bone marrow in an
EDTA (lavender-top) tube. Whole blood or
bone marrow is shipped at room temperature or refrigerated (cold
packs). Do not freeze whole blood or bone marrow.
After collection of the sample, draw date and time, as well as
sample type, must be written on the tube and included as requested
information. Ship sample immediately, due to short stability of 72
hours. If the stability of the sample cannot be determined, delay
in result or cancellation of test may occur.
Test Code

Includes
If P210 transcript expression was previously documented, only P210 BCR-ABL1 will be performed at an additional charge (CPT code: 81206).
If no prior positive is documented P190 BCR-ABL1 and P210 BCR-ABL1 will be performed at an additional charge (CPT code(s): 81206, 81207).
Preferred Specimen
6 mL whole blood or 3mL bone marrow
Minimum Volume
Whole blood: 4 mL Bone marrow: 2 mL
Other Acceptable Specimens
Instructions
Do not reject specimens, send to laboratory for screening.
Collect 4 mL of whole blood or 3 mL bone marrow in an EDTA (lavender-top) tube. Whole blood or bone marrow is shipped at room temperature or refrigerated (cold packs). Do not freeze whole blood or bone marrow.
After collection of the sample, draw date and time, as well as sample type, must be written on the tube and included as requested information.
If the stability of the sample cannot be determined, delay in result or cancelation of test may occur. Clotted specimens are unacceptable.
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.
