Additional Technical Information
Ordering Recommendation

Order only for patients with an established diagnosis of a BCR-ABL1 positive leukemia. This test is used to determine if a mutation is present that would interfere with response to TKI therapy in Philadelphia chromosome positive (Ph+) lymphoblastic leukemia or chronic myelogenous leukemia (CML). The test detects all common mutations, including T315I. For initial BCR-ABL1 testing, refer to BCR-ABL1, Qualitative with Reflex to BCR-ABL1 Quantitative (2005010).
