The Food and Drug Administration has cleared Bio-Rad’s digital polymerase chain reaction (PCR) testing solution to monitor patients’ molecular response to treatment for chronic myeloid leukemia.
The QXDx AutoDG ddPCR System combines Bio-Rad’s Droplet Digital PCR technology and the QXDx BCR-ABL %IS Kit, according to the.
This so-called liquid biopsy test can “precisely and reproducibly” monitor the molecular response to tyrosine kinase inhibitor therapy. The current standard – reverse transcription quantitative PCR – can have variable results, especially at low levels of disease, according to Bio-Rad.
FDA clearance means that the product is “substantially equivalent” to an already-approved product and can be sold in the United States, according to the.
