What Does a High Red Cell Distribution Width SD Mean?

1. A high red cell distribution width (RDW) in a blood test indicates abnormal red blood cell (RBC) volume in peripheral blood, generally related to treatment factors and RBC DNA synthesis disorders.

2. During the examination, RDW-SD (Standard Deviation) can reflect the size and dispersion index of RBCs in peripheral blood. If the RDW-SD value is high, it indicates a significant difference in the volume of peripheral RBCs, necessitating prompt cooperation with doctors to complete further examinations to help identify the cause.

3. Iron deficiency anemia and post-transfusion treatment may be related to blood circulation and drug factors, generally recovering without special treatment. RBC DNA synthesis disorders can also lead to a high RDW, related to reasons such as vitamin B12 and folate deficiency in the body. Drug treatment can be conducted as per doctors' advice to help improve the condition, such as vitamin B12 tablets and folate tablets.

4. After a high RDW is detected, active treatment is recommended. During treatment, timely follow-up visits to the hospital are necessary to avoid other diseases caused by abnormal RBCs.
