Guidelines for RQ-PCR MRD

EuroMRD's interpretation guidelines define how RQ-PCR-based MRD data should be categorized and reported. These guidelines are what makes an 'MRD negative' or 'MRD positive' result mean the same thing regardless of which center generated it. The current guidelines were most recently updated in 2024, building on the original 2007 framework.
