- PowerPath Code BCR-ABL p190
- Schedule Monday - Friday (Variable)
- Turn Around Time 4-7 days
- Disease State Acute Lymphoblastic Leukemia (ALL), Chronic Myelogenous Leukemia (CML)
- Methodology Reverse-Transcriptase and real-time (RT-qPCR) polymerase chain reaction to measure the quantity of BCR-ABL1 fusion transcript p190 (e1a2)
Minimum of 1 mL whole blood in a purple (EDTA) or pink top tube (EDTA);
Minimum of 1 mL of bone marrow aspirate in a purple, pink, or green (heparin) top tube.
Presence of the BCR-ABL1 fusion transcript is seen in a majority of patients with CML, and in a subset of patients of B-ALL. Quantitative monitoring of the BCR-ABL1 transcript can act as a diagnostic tool and provide guidance during therapy.
Monitoring therapy in patients with CML or other BCR-ABL1 positive neoplasms with known ela2 fusion transcript. The transcript level for the minor breakpoint (p190) is reported as the NCN% ratio of BCR-ABL1 to ABL1.
