Iron & Ferritin Saturation Index Calculator

An isolated **Ferritin** check is frequently misleading. Because Ferritin acts as an acute-phase reactant, acute inflammation, minor infections, or intense workouts can artificially spike it.

To evaluate true iron depletion (anemia) or iron overload (hemochromatosis), clinicians calculate **Transferrin Saturation** alongside **UIBC (Unsaturated Iron-Binding Capacity)**.

Diagnostic Guidelines: * Saturation < 20%: Strong indicator of cellular iron depletion or iron deficiency anemia, even if Ferritin appears mid-range due to inflammatory masking. * Saturation 20% to 45%: Healthy, balanced physiological iron absorption and transport limits. * Saturation > 50%: Elevated iron saturation. Suggests potential systemic iron accumulation or genetic Hemochromatosis, requiring clinical management.
