HelpTest ID B210R BCR/ABL1, p210, mRNA Detection, Reverse Transcription-PCR (RT-PCR), Quantitative, Reflex, Varies
Specimen Required
Only orderable as a reflex. See BCRFX /BCR/ABL1 Qualitative Diagnostic Assay with Reflex to BCR/ABL1 p190 Quantitative Assay or BCR/ABL1 p210 Quantitative Assay, Varies.
Useful For
Diagnostic workup of patients with a high probability of BCR-ABL1-positive hematopoietic neoplasms, particularly chronic myeloid leukemia and Ph+ acute lymphoblastic leukemia (B-lymphoblastic leukemia), to provide a pretreatment quantitative level of BCR-ABL1 mRNA transcript if the initial diagnostic reverse transcription polymerase chain reaction screen is positive
When positive, the reflex test provides a quantitative value for the corresponding e13-a2 or e14-a2 (p210) BCR-ABL1 mRNA fusion variant
