Special Info
Serum, plasma, and specimens collected in anticoagulants other than EDTA are unacceptable. Frozen, clotted or severely hemolyzed specimens will be rejected. For specimens having no t(9;22) fusion, this test will be canceled, and an ABL1 amplification confirmation test will be ordered. This test is New York DOH approved.
Clinical Info
Order only for patients with an established diagnosis of a BCR-ABL1 positive leukemia. 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). This test detects all common mutations, including T315I.
