Medical Devices; Immunology and Microbiology Devices; Classification of the DNA-Based Test To Measure Minimal Residual Disease in Hematological Malignancies

The Food and Drug Administration (FDA, Agency, or we) is classifying the DNA-based test to measure minimal residual disease in hematological malignancies into class II (special controls). The special controls that apply to the device type are identified in this order and will be part of the codified language for the DNA-based test to measure minimal residual disease in hematological malignancies classification. We are taking this action because we have determined that classifying the device into class II (special controls) will provide a reasonable assurance of safety and effectiveness of the device. We believe this action will also enhance patients' access to beneficial innovative devices, in part by reducing regulatory burdens.
