“…Although this technique can detect all mutations spanning the TKD domain, it has lower sensitivity and a longer turnaround time, and is more laborious than other available techniques, such as real-time PCR and droplet digital PCR (dd-PCR). Recently, several studies have demonstrated the application of next-generation sequencing (NGS) techniques, which are superior for the deep molecular early identification and monitoring of single and compound/polyclonal BCR :: ABL1 TKD mutations in CML [48] , [49] , [50] , [51] , [52] , [53] . However, NGS is only available in some laboratories and is difficult to standardize.…”
