What causes elevated ferritin?

Elevated ferritin levels can be caused by several factors, including iron overload conditions such as hemochromatosis, chronic inflammation, and liver disease. Inflammatory conditions, infections, and certain cancers can also lead to increased ferritin as part of the body's acute phase response. Additionally, excessive iron intake or repeated blood transfusions can contribute to higher ferritin levels. It's important to assess the underlying causes through further medical evaluation.
