Erythrocyte distribution width sd is a parameter that reflects the heterogeneity of peripheral blood erythrocyte volume, and its low value often represents the suppression of bone marrow hematopoiesis, which needs to be observed in combination with other indicators.
Erythrocyte distribution width sd is a routine blood test that reflects the uniformity of red blood cell volume. If it is low, it usually indicates that the size of red blood cells is more uniform, and other indicators of blood routine are within the normal range, so no special treatment is needed.
If the average red blood cell volume is small, it is considered to be iron deficiency anemia or thalassemia; if it is large, it is considered to be megaloblastic anemia.
This value alone is not clinically significant and needs to be seen in conjunction with other indicators. If these problems are encountered, it is recommended that the patient go to the hospital to identify the cause of the problem and to correct the anemia.
