Additional Codes

EPIC EAP  Mayo
LAB3338 BCRFX


Ordering Guidance


This test should not be used to monitor BCR::ABL1 fusion forms.

 

To monitor patients carrying BCR::ABL1 fusion forms coding for the p190 (e1/a2) protein, order BA190 / BCR::ABL1, p190, mRNA Detection, Reverse Transcription-PCR (RT-PCR), Quantitative, Monitoring Assay, Varies.

 

To monitor patients carrying BCR::ABL1 fusion forms coding for the p210 (e13/a2 or e14/a2) protein, order BCRAB / BCR::ABL1, p210, mRNA Detection, Reverse Transcription-PCR (RT-PCR), Quantitative, Monitoring Chronic Myeloid Leukemia (CML), Varies.

 

To monitor patients carrying rare BCR::ABL1 fusion forms coding for e19a2, e13/e14a3, e1a3, e6a2, e19a3, e8a2, e12a2, e6a3, e8a3, and e12a3, order BARQ / BCR::ABL1, Rare Fusion Monitoring, Quantitative, Varies.

 

If the patient has a previous positive history of p190, p210, or rare fusion forms, this test will be cancelled and one of the following appropriate monitoring tests will be added:

-BA190 / BCR::ABL1, p190, mRNA Detection, Reverse Transcription-PCR (RT-PCR), Quantitative, Monitoring Assay, Varies

-BCRAB / BCR::ABL1, p210, mRNA Detection, Reverse Transcription-PCR (RT-PCR), Quantitative, Monitoring Chronic Myeloid Leukemia (CML), Varies

-BARQ / BCR::ABL1, Rare Fusion Monitoring, Quantitative, Varies

 

If the specimen is greater than 72 hours post-collection when received, this test will be canceled and BADX / BCR::ABL1, Qualitative, Diagnostic Assay, Varies will be added and performed as the appropriate test if the specimen is still within stability for that test.
