The aim of the study was the evaluation of serum iron and calcium parameters in patients with renal function test and analysis of the relationships between serum level of iron and calcium in women and men according to age in group’s examined. Therefore, this study was carried out to investigate iron and calcium status in renal inflammation. The blood samples were analyzed for serum iron, urea, uric acid, creation and calcium level. Significantly decreased levels of serum iron, calcium and increased level of serum urea, uric acid and creatinine (p<0.0001).
