(Serum Iron / TIBC) * 100

Measured iron divided by the Total Iron Binding Capacity. Reflects iron availability for erythropoiesis.

Iron 60, TIBC 300 -> TSAT 20%.

Normal values are typically between 20% and 50%.

Usually indicates iron deficiency anemia, where there is not enough iron to fill the available transferrin.

Usually indicates iron overload states, such as hereditary hemochromatosis.
