The Serum Iron test is a blood test that measures the amount of iron circulating in the bloodstream. Iron is an essential mineral required for the production of hemoglobin, the protein in red blood cells that carries oxygen throughout the body. It also plays an important role in energy production, muscle function, immune health, and overall cellular function. Measuring serum iron levels helps evaluate the body’s iron balance and overall nutritional status.
This test is commonly recommended when a person experiences symptoms such as fatigue, weakness, dizziness, pale skin, shortness of breath, frequent infections, or when a doctor suspects iron-related disorders. It helps diagnose and monitor conditions such as iron deficiency anemia, nutritional deficiencies, chronic blood loss, iron overload disorders such as hemochromatosis, liver disease, and other conditions affecting iron metabolism. The Serum Iron test is often performed along with ferritin, Total Iron Binding Capacity (TIBC), and other iron studies to provide a complete evaluation of iron status and guide appropriate treatment when abnormalities are detected.
