What the test looks for
Detection and quantification of the BCR-ABL1 fusion transcript by quantitative RT-PCR.
At diagnosis, the test identifies the transcript type. During treatment with a tyrosine kinase inhibitor, the result is expressed as a percentage on the International Scale (BCR-ABL1/ABL1 IS) to assess the molecular response.
Required sample
- Whole blood on EDTA: 2 tubes of 5 mL, or bone marrow on EDTA.
