Ferritin Analysis

Meaning

Ferritin Analysis is a common clinical laboratory test that measures the concentration of ferritin protein in the blood, serving as the most reliable indicator of the body’s total iron storage capacity. Ferritin is the primary intracellular protein that stores iron in a non-toxic form and releases it in a controlled manner. Low ferritin levels are highly specific for iron deficiency, a condition that profoundly impacts energy production, thyroid function, and cellular oxygen transport. Conversely, elevated levels can indicate inflammation, liver disease, or iron overload conditions like hemochromatosis, requiring careful clinical differentiation.
