Iron is an essential part of our body and it is needed for the formation of Red Blood Cells. Serum Iron studies are used to evaluate the total amount of Iron present in the blood and the test has several components including total serum iron, total iron binding capacity and transferrin saturation test.
Iron is an an important constituent of hemoglobin and one of the vital nutrient that is needed in small quantities to help form normal red blood cells (RBCs). Iron test is done to estimate the amount of iron in the blood circulation , iron metabolism and the amount of stored iron in the body.
To evaluate amount of iron in the blood.
The test has components like serum iron, total iron-binding capacity, unsaturated iron binding capacity or transferrin saturation test. All these help to detect the amount of iron stored in the body and the body's capacity to absorb iron.
