General additional information

This test is MRD monitoring for patients with BCR::ABL1 E13A2/E14A2 transcript only (often termed P210).   For patients with other BCR::ABL1 fusion transcript types this test is not appropriate.  For patients with BCR::ABL1 E1A2 transcript please see MRD monitoring for BCR::ABL1 E1A2.

For suspected CML samples, refer to BCR::ABL1 diagnostic test and for AML and ALL diagnostic samples refer to AML and ALL panel testing respectively. 

This assay is performed to quantify E13A2 and/or E14A2 BCR::ABL1 transcripts in patients known to carry this specific fusion transcript.

Monitoring of the level of BCR::ABL1 fusion transcript is vital for the assessment of response to tyrosine kinase inhibitor therapy and the early identification of therapy resistance. BCR::ABL1 RT-qPCR monitoring is indirectly calibrated against primary WHO reference standards and is reported on the International Scale.

For patients demonstrating a significant rise in BCR::ABL1/ABL1 ratio, an assessment for BCR::ABL1 tyrosine kinase domain testing is available.
