This document specifies the requirements, labeling and instructions for use, packaging, transportation and storage of breakpoint cluster region-Abelsonian leukemia virus (BCR-ABL) fusion gene detection kits, and describes the corresponding test methods. This document is suitable for detecting breakpoint cluster area-Abelson leukemia virus (BCR-ABL) fusion gene detection kit in peripheral blood samples and bone marrow samples. The technical methods used include fluorescent polymerase chain reaction (Polymerase Chain Reaction, PCR) ) method, fluorescence reverse transcription polymerase chain reaction (Reverse Transcription-Polymerase Chain Reaction, RT-PCR) method, reverse transcription digital polymerase chain reaction (Reverse Transcription- Digital Polymerase Chain Reaction, RT-dPCR) method and digital polymerase reaction (Digital Polymerase Chain Reaction, dPCR) method, etc.
