Description

A Ferritin Serum Test is ordered to measure the amount of ferritin in the blood, which is an indicator of iron stores in the body. The test can indicate the presence and severity of iron deficiency or iron excess.

The Ferritin blood test is often ordered when a person has abnormal CBC results such low hemoglobin and hematocrit which may be indicative of anemia caused by iron deficiency.

Most iron stored in the body is bound to a protein known as ferritin. Most often found in the liver, spleen, bone marrow and muscles, ferritin is found in smaller concentrations in your blood, however the amount indicates how much iron is stored in your body. If your diet lacks iron, your body begins to use its iron stores, and ferritin levels drop. Ferritin levels can increase when the body absorbs more iron than it needs. Consequently, low ferritin levels may indicate iron deficiency, while high levels can indicate iron overload or hemochromatosis, a condition in which the body accumulates too much iron. A Ferritin Test is often ordered along with other tests such as an iron serum test, iron and TIBC blood test and/or transferrin test to diagnose various iron-related diseases.
