The technique that is commonly adopted for measuring the BCR-ABL1 transcript is the quantitative PCR, which could be performed either by real-time or dPCR; the new published data have shown that dPCR could be more sensitive and accurate than RQ-PCR and, in future, we'll see if dPCR will replace RQ-PCR in the CML context. The gene discussed is ABL1; the disease is chronic myelogenous leukemia, BCR-ABL1 positive.
