BCR-ABL1 Transcript Detection for Chronic Myelogenous Leukemia (CML) and Acute Lymphocytic Leukemia (ALL), Quantitative

Laboratory assay overview

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.

Verify these ranges and sources

We compile every detail above directly from named laboratory directories and published clinical studies. Laboratories calculate standard reference intervals from the statistical distribution of tested populations for a specific assay method and demographic group, rather than setting universal optimal targets.
