Intended Use
Use in conjunction with conventional cytogenetics for diagnosis, prognosis, and monitoring of MDS. Dysplasia in one or more myeloid lineages is the morphological hallmark of MDS. The threshold for dysplasia is set at 10% for all lineages and across all MDS types, as well as for myelodysplastic/myeloproliferative neoplasms.
