This assay is used for the in vitro quantitative determination of ferritin in human serum, plasma, and whole blood. It aids in diagnosing disorders related to iron metabolism, such as iron deficiency anemia and hemochromatosis. Ferritin reflects the body’s iron storage status, with low levels indicating deficiency and high levels suggesting iron overload. Ferritin is a spherical protein composed of 24 subunits, with an iron core that stores up to 4500 iron atoms. It helps store iron for biological use and protects cells from iron toxicity. Detection methods commonly used include chemiluminescence and fluorescence immunoassay.
