BCR-ABL1 Transcript Detection by RT-PCR

Quantitative – Quantitative BCR-ABL1 Translocation Detection by RT-PCR for CML and ALL

Clinical Use:

This assay can detect three different types of BCR-ABL1 fusion transcripts associated with CML, ALL, and AML:e13a2 (previously b2a2) and e14a2 (previously b3a2) (major breakpoint, p210), as well as e1a2 (minor breakpoint, p190). The e13a2 and e14a2 transcript values are titrated to the current International Scale (IS). The standardized baseline is 100% BCR-ABL1 (IS) and major molecular response (MMR) is equivalent to 0.1% BCR-ABL1 (IS) corresponding to a 3-log reduction. Results should be correlated with appropriate clinical and laboratory information as indicated.
