ferritinszintek

Ferritin levels, also called ferritinszintek in Hungarian, refer to the amount of ferritin in the blood and are used as a marker of the body's iron stores. Ferritin is a protein that stores iron and releases it in a controlled way, mainly within cells in the liver, spleen, and bone marrow. Serum ferritin generally reflects total body iron stores, but levels can be influenced by inflammation, infection, liver disease, and other conditions. Blood tests measure ferritin in nanograms per milliliter (ng/mL).

Interpretation of ferritin levels varies with context. Low ferritin typically indicates depleted iron stores and often accompanies iron deficiency anemia. Very high ferritin can signal iron overload conditions such as hemochromatosis, but it can also rise with acute or chronic inflammation, infection, liver disease, certain cancers, or metabolic syndrome. Because ferritin is an acute‑phase reactant, its value may be elevated even when iron stores are normal or reduced during inflammatory states; therefore, interpreting ferritin requires consideration of the clinical picture and other tests.

Clinicians commonly use ferritin alongside other iron parameters, including transferrin saturation and serum iron, as well as inflammatory markers like C-reactive protein, to assess iron status. Monitoring ferritin over time can help evaluate response to iron supplementation or iron‑reducing strategies in overload conditions. Testing guidelines and reference ranges vary by laboratory and by age, sex, and physiological status such as pregnancy, so results should be interpreted by a healthcare provider within the full clinical context.
