Elevated rdw is an elevated value of erythrocyte distribution width, and in thalassemia, which is a form of thalassemia, an elevated rdw may be thalassemia, but it may not be.
Based on the analysis of the red cell distribution width in combination with the mean red cell volume, the anemia can be classified morphologically, which is especially important for the differentiation between iron deficiency anemia and thalassemia. If the mean erythrocyte volume is decreased and the erythrocyte distribution width is increased, it is common in β-thalassemia, iron deficiency anemia, hemoglobin S disease, and hemoglobin H disease.
It can be seen that an elevated red cell distribution width may be thalassemia, but it may also be other types of anemia such as iron deficiency anemia.
Thalassemia, also known as dysglobinopoietic anemia, is an inherited hemolytic disorder caused by a disorder in the synthesis of one or more of the normal peptide chains of globin. Most patients with thalassemia minor have a good prognosis, and patients with severe forms improve their symptoms with treatment, but they are also at risk of death. Medications include Deferasirox, among others.
Test results showing an elevated red blood cell distribution width should be consulted with a physician to clarify the cause and, if necessary, treated under the direction of a physician.
