Ferriitteina

Ferritina is a protein found in the body that stores iron. It is composed of a protein shell made of subunits called apoferritin, which encloses an iron core. This complex allows for the safe storage and controlled release of iron, a vital mineral for many bodily functions, including oxygen transport by red blood cells and energy production.

Ferritin is primarily found in cells within the liver, spleen, and bone marrow, where iron metabolism is concentrated. However, small amounts of ferritin are also present in the bloodstream. The level of ferritin in the blood is often used as an indicator of the body's total iron stores.

Low ferritin levels can suggest iron deficiency, a condition that can lead to anemia. Conversely, high ferritin levels can indicate iron overload, which can occur in certain genetic disorders like hemochromatosis or as a result of frequent blood transfusions. Elevated ferritin can also be a sign of inflammation or infection, as ferritin is an acute-phase reactant, meaning its levels can increase in response to inflammation. Monitoring ferritin levels is therefore a common diagnostic tool for a range of conditions related to iron status and inflammation.
