Useful For

Diagnostic workup of patients with a high probability of BCR-ABL1-positive hematopoietic neoplasms, predominantly chronic myeloid leukemia and acute lymphoblastic leukemia

Method Name

Reverse Transcription-Polymerase Chain Reaction (RT-PCR) Multiplex PCR

Reporting Name

BCR/ABL1, RNA-Qual, Diagnostic

Specimen Type

Varies


Ordering Guidance


This test is only qualitative and should not be used for routine monitoring (ie, quantitative messenger RNA [mRNA] level).

 

Monitoring of most patients with chronic myeloid leukemia (CML) should be performed using BCRAB / BCR/ABL, p210, mRNA Detection, Reverse Transcription-PCR (RT-PCR), Quantitative, Monitoring Chronic Myelogenous Leukemia (CML), Varies.

 

Monitoring of patients known to carry a p190 fusion should be performed using BA190 / BCR/ABL, p190, mRNA Detection, Reverse Transcription-PCR (RT-PCR), Quantitative, Monitoring Assay, Varies.
