Used in biomedical research to quantitatively measure ferritin levels in human serum, plasma, and other biological fluids. This ELISA kit helps assess iron storage and metabolism in clinical studies, aiding in the diagnosis and monitoring of iron-related disorders such as iron deficiency anemia and hemochromatosis. It is also employed in inflammation and chronic disease research since ferritin acts as an acute-phase reactant. The kit provides a sensitive and specific tool for high-throughput screening in laboratories focused on nutritional assessment, immune response, and metabolic health.
