This quantitative test is appropriate for therapeutic monitoring of BCR-ABL1 major (p210) positive chronic myeloid leukemia (CML) or acute lymphoblastic leukemia/lymphoma (ALL). This test is designed to meet the current National Comprehensive Cancer Network (NCCN) guidelines and is recommended for detection of minimal residual disease (MRD).
For patients with uncertain diagnoses or unknown forms of BCR-ABL1 fusion transcripts, consider ordering Diagnostic Qualitative BCR-ABL1 Assay with Reflex to p190 or p210 Quantitative Assays (3005839).
Reverse Transcription Polymerase Chain Reaction
RNA isolation: Sun-Sat
New York DOH Approval Status
Whole blood or bone marrow in lavender (EDTA).
Whole blood: Transport 5 mL whole blood. (Min: 3 mL)
Bone marrow: Transport 3 mL bone marrow. (Min: 1 mL)
Refrigerate immediately. Specimens must be received within 48 hours of collection due to lability of RNA.
Whole blood and bone marrow: CRITICAL REFRIGERATED. Separate specimens must be submitted when multiple tests are ordered.
Serum, plasma, ambient or frozen bone marrow or whole blood, CSF, or FFPE tissue. Specimens collected in anticoagulants other than EDTA. Severely hemolyzed or clotted specimens.
Ambient whole blood and ambient bone marrow specimens past 7 days will be canceled. Refrigerated whole blood or bone marrow past 7 days will be canceled.
This quantitative test is recommended for therapeutic monitoring and detection of minimal residual disease for patients with an established diagnosis. For patients with uncertain diagnoses or unknown forms of BCR-ABL1 fusion transcripts, please order 3005839 Diagnostic Qualitative BCR-ABL1 Assay with Reflex to p190 or p210 Quantitative Assays.
Ambient: Unacceptable; Refrigerated: 48 hours; Frozen: Unacceptable

This test was developed and its performance characteristics determined by ARUP Laboratories. It has not been cleared or approved by the U.S. Food and Drug Administration. This test was performed in a CLIA-certified laboratory and is intended for clinical purposes.
Laboratory Developed Test (LDT)
This test does not detect the BCR-ABL1 micro (p230) or minor (p190) fusion transcripts. This test does not detect rare BCR-ABL1 major (p210) forms involving beyond ABL1 exon 2.
For the p190 fusion form (minor breakpoint), order BCR-ABL1, Minor (p190), Quantitative (ARUP test code 2005016).
