Ferritin

Ferritin is a protein that stores iron, and serves as an important marker for the body's iron reserves. The laboratory value measures the concentration of ferritin in the blood and is often used to diagnose iron deficiency or iron overload.

A ferritin test is recommended for: Persons with symptoms such as fatigue, paleness or shortness of breath (indication of iron deficiency anemia) Women with heavy menstrual bleeding Pregnant or breastfeeding women (high iron requirement) People with chronic diseases (e.g. chronic kidney failure or inflammatory bowel diseases) Persons suspected of having hemochromatosis (a genetic disease with iron overload)

The test helps to evaluate the body's iron supply. Ferritin is a sensitive marker for iron deficiency, even before anemia develops. In case of suspected iron overload, the test also provides valuable clues.

A low ferritin value indicates an iron deficiency, which is often caused by blood loss, unbalanced diet, or malabsorption. Symptoms of iron deficiency are: Fatigue and reduced performance Pale skin Brittle nails or hair loss An elevated ferritin value can indicate iron overload, inflammation, or chronic diseases such as liver diseases.

A test is useful in the case of symptoms of iron deficiency or in risk groups, such as women with heavy bleeding, pregnant women or people with chronic illnesses. The test can be carried out at any time of the day and is independent of food intake.

Ferritin is a so-called acute phase protein value and can be elevated in inflammation or infection, even if there is no iron overload. An investigation of conspicuous ferritin values should therefore be carried out, if necessary, in the context of other iron parameters such as transferrin. Vegetarians and vegans often have lower iron values, as plant-based iron is less efficiently absorbed.
