IDA Diagnosis: Ferritin

IDA Diagnosis: Ferritin

Measuring Ferritin Concentration

To differentiate iron deficiency anemia from other types of anemia, your doctor may take a sample of your blood to measure its concentration of ferritin. (Ferritin is the primary protein that allows your body to store iron in its cells.)1

Ferritin levels that are lower than normal typically indicate iron deficiency. The most common cause of elevated ferritin is inflammation, another possible cause of anemia.1

Ferritin levels are a good indicator of iron deficiency anemia and will help your doctor rule out other types of anemia associated with inflammation, liver or kidney disease, or certain blood diseases such as thalassemia minor (an inherited disease that's common in people from Mediterranean countries).1,2,3
