FERRITIN Detail

The Ferritin test determines the amount of ferritin in the blood — a protein that stores iron and releases it as needed by the body. Ferritin acts as a marker of the body's total iron stores.

Low ferritin levels typically indicate iron deficiency, which can lead to anemia, fatigue, weakness, and impaired immune function. Elevated ferritin levels may be seen in conditions such as hemochromatosis (iron overload), chronic infections, liver disease, or inflammatory disorders.

This test is commonly used alongside other iron tests (like serum iron, TIBC, and transferrin saturation) to diagnose and monitor anemia, assess iron metabolism, and evaluate overall iron status in the body.
