Tests now and in the future
| Purpose . | Test now . | Test soon . | Faster? . | Cheaper? . | Better? . |
|---|---|---|---|---|---|
| Detection of Ph | Cytogenetics, fluorescence in situ hybridization | In situ BCR-ABL1 protein assay | Yes | No | Quantitation of protein targets could be clinically useful |
| BCR-ABL1 mRNA detection | qRT-PCR | Digital PCR | Yes | No | Potentially more accurate, sensitive, and robust |
| BCR-ABL1 DNA detection | Multiplex PCR and sequencing | NGS sequencing or real-time sequencing | Yes | No | Could simplify BCR-ABL1 DNA testing |
| ABL TKD mutation testing | Sanger or NGS | Ultrasensitive NGS | No | No | Great sensitivity, but unclear which clinical settings will benefit |
| Diagnosis and monitoring in low-income areas | Some local, but more outsourced testing | Dried blood spots or point-of-care devices | Yes | Yes | Potentially gets the test to more patients. Lack of sensitivity compared with standard PCR |
