Sensitive and quantitative monitoring of BCR-ABL mRNA in patients with chronic myelogenous leukemia (CML)
The ongoing presence of the Ph chromosome in ALL patients after consolidation therapy is a significant predictor of relapse, and monitoring is recommended. Established international organizations recommend definitive timepoints for monitoring BCR-ABL p190 in ALL and CML patients.7-10 Unlike the BCR-ABL World Health Organization international standard (WHO IS) for the p210 transcript, currently, there are no international standards that can be used to standardize the p190 fusion transcript, posing a challenge for a quantitative assay monitoring p190 transcript level.
Current testing options for BCR-ABL p190 monitoring for both CML and ALL patients are not only cumbersome, but can be expensive and time consuming for the lab to implement because:
- Available testing methods can be complex and create inefficient laboratory workflows.
- No international scale has been established for p190 monitoring, so laboratories are dependent on ratios and must run laborious standard curves.
Xpert BCR-ABL Ultra p190 is an automated test for quantifying the amount of BCR-ABL p190 transcript as a ratio of BCR-ABL p190/ABL with high sensitivity.
Based on the innovative GeneXpert® technology, Xpert BCR-ABL Ultra p190 automates the testing procedure, including RNA isolation, reverse transcription, and fully nested real-time PCR of BCR-ABL target gene and ABL reference gene in one automated cartridge.
Leveraging Cepheid’s lab in a cartridge™ technology, the Xpert BCR-ABL p190 test decreases workflow complexity and hands-on time by automating the entire testing process, delivering faster results.
Xpert BCR-ABL Ultra p190 is a quantitative test for the BCR-ABL minor breakpoint (p190) transcripts that provide high test sensitivity, standardization, and on-demand molecular results in ≤2.5 hours. With minimal hands-on time and a streamlined workflow, Xpert BCR-ABL Ultra p190 eliminates the need for time-consuming hands-on processes and enables the laboratory to run p190 testing in-house.
Simple & Easy to Use
- ≤2.5 hours total testing process
- Simply add treated blood sample and an off-board reagent to the Xpert cartridge
Sensitive & Robust Design
- Includes two internal controls
- 4 mL input volume of EDTA whole blood supports high test sensitivity for detection of low-level transcripts
- High sensitivity and low inter-laboratory variation11
- Clinically demonstrated limit of detection of 0.0065%11
