Background: The estimation of ferritin and related variables by complete serum iron profile, for Iraqi hashimoto’s patients to see the effect of thyroid hormone insufficiency, which may lead to deficiency of ferritin iron stores, this may be quite useful during the diagnosis and treatment of hashimoto’s patients. Patients and Method: The study was performed at National Center of Teaching laboratories of Medical city institute in Baghdad. Fifty newly diagnosed patients with hashimoto’s and forty apparently healthy controls. Diagnosis based on thyroid profile analysis including:Thyroid Stimulating Hormone (TSH), Thyroxine (totalT4) and Triiodothyronine (total T3), estimation of antibodies against thyroperoxidase, iron profile including: serum ferritin, serum iron, total iron-binding capacity (TIBC), unsaturated iron-binding capacity (UIBC) and Transferrin saturation (TSAT) for both groups. Result: The hashimoto’s patients have elevated levels of anti-TPO, TSH, TIBC, UIBC and TSATas compared with controls. Anti-TPO, TSH, UIBC and TSAT were significantly higher than that of controls, while TIBC is not significant. In other hand, hashimoto’s patients have lowered levels of Total T3, Total T4, Ferritin and Iron as compared with controls. Total T4, Ferritin and Iron were significantly lower than that of control,while TotalT3 is not significant. Conclusion: Statistical application for the current study by employing Receiver Operation Characteristic curve (ROC curve) shows the validaty of anti-TPO in addition to serum iron and total T4 to be used as a biomarkers for detection of hashimoto’s thyroiditis.
