BCR/ABL p210, Quant Reflexive

General Information

Lab Name

BCR/ABL p210, Quant Reflexive

Lab Code

QP210R

Epic Name

BCR/ABL p210, Quant Reflexive

Description

This assay is a nucleic acid amplification test for the quantitation of BCR::ABL1 p210 transcripts (e13a2 and e14a2) in total RNA from whole blood or bone marrow aspirate. This quantitative test is recommended for patients with uncertain diagnosis or unknown forms of BCR::ABL1 fusion. The test does not differentiate between e13a2/b2a2 or e14a2/b3a2 fusion transcripts and does not detect other rare fusion transcripts resulting from t(9;22). For samples with not detected BCR::ABL1 p210 transcripts, BCR::ABL1 p190, Quant by RT PCR [QP190] will be ordered.

To facilitate the interlaboratory comparison of findings and the assessment of molecular milestones (major molecular response or MMR), results are reported using the International Scale.

The reportable range is 0.0030% to 50% IS

The limit of detection is 0.0030% IS.

Stability is 72 hrs. Specimens received after 72 hrs. will be rejected.

Limitations: This assay in unable to detect BCR::ABL1 p190, p230, or other rare transcripts.
