Unsaturation Iron Binding Capacity(UIBC) Determination Reagent is an in vitro diagnostic quantitative test kit.This test is used for diagnosis and treatment of diseases such as iron deficiency anemia, hemochromatosis and chronic renal disease. Because normally only about one third of the iron binding sites of transferrin are occupied by Fe (III), serum transferrin has considerable reserve Iron Binding Capacity. This is called the serum Unsaturated Iron Binding Capacity (UIBC)
