  • BCR-ABL1 Transcript Detection for Chronic Myelogenous Leukemia (CML) and Acute Lymphocytic Leukemia (ALL), Quantitative 480481

    5 analytes · Blood · Fasting not stated · Turnaround 5 - 7 days

    Method and collection
    Method
    Total RNA is isolated from the sample and subject to a real-time, reverse transcriptase polymerase chain reaction (RT-PCR). The PCR primers and probes are specific for BCR-ABL1 e13a2, e14a2 and e1a2 fusion transcripts. The ABL1 transcript is amplified as the control for cDNA quantity and quality. Serial dilutions of a validated positive control RNA with known t(9;22) BCR-ABL1 are used as reference for quantification of BCR-ABL1 relative to ABL1 . The numeric BCR-ABL1 level is reported as % BCR-ABL1/ABL1 and the detection sensitivity is 4.5 log below the standard baseline (<0.0032%).
    Collection
    Submit at room temperature. Specimens should arrive in the laboratory within 48 hours of collection. Indicate date and time of collection on test request form.

We compile this page from named laboratory catalogs, guidelines and studies. Labs calculate reference intervals from the people they test, for one assay method and one population group, so an interval describes that population rather than an optimal target.
