Ferritin is a protein that stores iron in your cells. It's the most sensitive single test for detecting iron deficiency, often becoming abnormal before other iron markers or CBC results change. Low ferritin can cause fatigue, weakness, hair loss, and difficulty concentrating even before frank anemia develops. It's also an acute phase reactant, meaning it can be elevated during inflammation or infection.
