MDS WITH SINGLE LINEAGE DYSPLASIA (MDS-SLD)
MDS-SLD exhibits a low number of one to two types of blood cells in the bloodstream and one type of blood cell looks abnormal (dysplasia) in the bone marrow. For the affected cell type, at least 10% of the cells look abnormal (dysplasia). Less than 5% of cells in the bone marrow are blast (immature) cells with no blasts in the bloodstream.
