Serum ferritin levels may be elevated in patients who have both iron deficiency and chronic inflammation, making the distinction between iron deficiency anemia and the anemia of chronic disease difficult. Mulherin et al developed a simple algorithm based on simple laboratory measures to help diagnose anemia in patients with rheumatoid arthritis. The authors are from Dublin, Ireland.
