Background: Many newer tests are now available to diagnose iron deficiency in CKD but these tests are not widely used in India as these tests are expensive and patients cannot afford these tests. Hence the traditional tests serum ferritin and transferrin saturation are needed to be studied more thoroughly to infuse IV iron to patients with iron deficiency anemia in CKD as many cannot afford ESAs and blood. Ferritin is an important indicator of iron overload as well as an acute phase reactant which increases in inflammatory conditions. Serum ferritin getting raised both in iron deficiency anemia and inflammatory states complicates our diagnosis. In this scenario TSAT plays important role in ruling out iron overload and inflammation is ruled out by inflammatory markers
