The iron test is used to measure the amount of iron that is carried by transferrin, a protein that transports iron from the intestine to cells that use iron. The amount of iron within the blood varies throughout the day, and from one day to the next. An iron blood (serum) test is therefore not a useful measure of iron status if it is used on its own. Serum iron is therefore often requested in combination with other tests of iron status.
