General additional information

This test is MRD monitoring for patients with the BCR::ABL1 E1A2 [p190] transcript only.

For patients with BCR::ABL1 E13A2/E14A2 [p210] transcripts please see MRD monitoring for BCR::ABL1 E13A2/E14A2 quantification.

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

This assay is performed to quantify BCR::ABL1 E1A2 [p190] transcripts in patients known to carry this specific fusion transcript.  It is not suitable for the quantification of other variant transcripts (e.g. E6A2, E19A2).

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. In contrast to E13A2/E14A2 fusion transcripts, no international scale is available for E1A2 fusion transcripts.
