Background: Type 2 diabetes mellitus (DM2) is an important health problem worldwide affecting about 8 percent of the population. Diabetes Mellitus is one of the most common chronic diseases in Sudan. These patients have many changes in their blood, and many factors affect the glucose tolerance that is mediated by insulin, one of these changes is S.ferritin level, a marker of iron storage. Increased serum ferritin, reflecting body iron overload, is often associated with insulin resistance. The role of iron in the pathogenesis of diabetes is suggested by an increased incidence of type2 diabetes mellitus in diverse causes of iron overload, and reversal or improvement in glycemic control with a reduction in iron load achieved using either phlebotomy or iron-chelating therapy.
Aim: To evaluate serum ferritin level in type-2 Diabetes Mellitus Sudanese Patients.
Materials and Method: A case-control study was done in 45diabetic patients and 45normal healthy individuals as a control group, including measurement of serum ferritin by an electrochemiluminescence immunoassay (ECLIA) method full automated chemical analyzer. COBAS e411 machine used Roche HITACHI Kit and quantification of HbA1c level by i-chroma instrument.
Results: The study showed that serum ferritin levels were significantly increased in diagnosed cases of type 2 diabetes mellitus in comparison with the age and gender-matched healthy individuals (P. value= 0.008). There was an insignificant correlation between serum ferritin and HbA1c(P. value=0.431). 
Conclusion: Therefore, the findings of the present study indicate that serum ferritin was increased in diabetes and this increase may contribute to the pathogenesis of this disease as well as to the development of complications. Thus, routine screening for serum ferritin concentration in pre-diabetes and diabetic patients should be done to assess the body's iron stores.
