Question

Quizplus · Accepted Answer

The diagnosis of refractory anemia with ringed sideroblasts requires the presence of at least 15% ringed sideroblasts in the bone marrow. Therefore, option D is the correct choice. A minimum of 30% ringed sideroblasts is seen in refractory anemia with excess blasts, while the presence of monoblasts is indicative of acute myeloid leukemia, but not specifically refractory anemia with ringed sideroblasts.
