Ferritin is a protein that stores iron in the body's cells. This test measures the amount of ferritin in the blood, which reflects the body's iron stores. It's a more accurate indicator of iron status than serum iron alone. Low ferritin levels suggest iron deficiency, while high levels can indicate iron overload or inflammation. This test is crucial for diagnosing and monitoring conditions such as anemia, hemochromatosis, and chronic diseases. It's often used in conjunction with other iron tests to provide a comprehensive picture of iron metabolism.
A low ferritin reading indicates iron deficiency, which can lead to anemia if left untreated. This may result from inadequate dietary iron intake, poor iron absorption, or chronic blood loss. Symptoms can include fatigue, weakness, pale skin, and shortness of breath. In women, heavy menstrual periods can be a common cause. Chronic conditions like celiac disease or inflammatory bowel disease can also lead to low ferritin. Treatment typically involves iron supplementation and addressing the underlying cause.
A high ferritin reading can indicate excess iron storage in the body, a condition known as iron overload or hemochromatosis. This can be due to genetic factors, frequent blood transfusions, or liver disease. High ferritin can also be a result of inflammation or infection, as ferritin is an acute phase reactant. Chronic conditions like rheumatoid arthritis or certain cancers can cause elevated ferritin. Excessive iron can damage organs, particularly the liver, heart, and pancreas. Further testing is usually required to determine the cause and appropriate treatment.
