Test Comments:  
Methodology: Quantitative Real-Time Polymerase Chain Reaction (PCR)
Clinical Significance: This reverse-transcription PCR-based assay detects the BCR-ABL1 transcript produced by the t(9;22) chromosomal translocation associated with chronic myelogenous leukemia (CML) and a subset of lymphoblastic leukemias. For the P190 transcript associated with the minor t(9;22) breakpoint in lymphoblastic leukemia, BCR-ABL1 transcript levels are expressed as a percent ratio of BCR-ABL1 to the normalizing ABL1 transcript. For the P210 transcript associated with CML, quantitation is further adjusted to the international scale (IS) to allow comparison with other IS-compliant BCR-ABL1 assays. Optimal therapy in CML is associated with transcript levels below the major molecular response (MMR) milestone indicated by a BCR-ABL1/ABL1 % (IS) below 0.1.
Documentation: CPT Coding
If P190 transcript expression was previously documented, only P190 BCR-ABL1 will be performed (CPT code(s): 81207).
If P210 transcript expression was previously documented, only P210 BCR-ABL1 will be performed (CPT code(s): 81206).
If no prior positive is documented, P190 BCR-ABL1 and P210 BCR-ABL1 will be performed (CPT code(s): 81206, 81207).
