Ferritin levels are typically reported in units such as nanograms per milliliter (ng/mL) or micrograms per liter (μg/L). Ferritin levels are used to assess the body’s iron stores, as ferritin is a storage form of iron.

Measuring ferritin levels can be helpful in diagnosing and monitoring conditions related to iron status, such as iron deficiency anemia or iron overload disorders like hemochromatosis. Ferritin levels can also be influenced by other factors, such as inflammation or liver disease, so it’s important to consider the overall clinical context when interpreting the results.
