Useful For
Detection of CBFB::MYH11 gene fusion in patients recently diagnosed with acute myeloid leukemia (AML)
Minimal residual disease monitoring during the clinical and therapeutic course of patients with AML
Highlights
This test is a highly sensitive quantitative assay for the detection of inv(16)(p13.1q22) or t(16;16)(p13.1;q22) CBFB::MYH11 gene fusion. This detection is useful for patients with acute myeloid leukemia at the time of diagnosis as well as for minimal residual disease monitoring during the clinical and therapeutic course of these patients.
