The blood also contains more blasts: between 5 and 19% of the white blood cells in the blood are blasts.The blasts may contain Auer rods.he number of blasts (very early cells) in the bone marrow is less than 5% and none of the blasts contain Auer rods (an abnormality seen in some leukemia cells). Blasts are rare or absent in the blood. RCMD changes into leukemia in about 10% of patients. Having this type of MDS will shorten a personâs life.
