Transferrin Saturation

Health

Calculate transferrin saturation (%) from serum iron and TIBC. Indicates iron status and hemochromatosis risk.

Formula

Transferrin Saturation (%) = (Serum Iron / TIBC) × 100

Iron 100, TIBC 350

Inputs
  • Serum Iron (µg/dL): 100
  • TIBC (µg/dL): 350

28.6% saturation (normal)

Frequently asked questions

Normal range?
Normal: 20-45%. <20% suggests iron deficiency; >45% suggests iron overload or hemochromatosis.
