Could Red Cell Distribution Width be a Marker in Hashimoto's Thyroiditis?

Abstract

Aims: Hashimoto's Thyroiditis (HT) is the most common autoimmune thyroiditis worldwide and characterized with lymphomonocytic inflammation of the thyroid gland. Red cell distribution width (RDW) reflects erythrocyte anisocytosis and besides it increases in iron deficiency anemia, recent studies reported that RDW was also associated with conditions characterized with overt or subclinical infl ammation. We aimed to answer whether RDW increased in Hashimoto's thyroiditis.
