Normal iron transferrin saturation is which percentage range?

Explanation:
Transferrin saturation shows how much iron-bound capacity of transferrin is actually filled by iron. It’s calculated as serum iron divided by total iron-binding capacity (TIBC) times 100. In healthy adults, the normal range is about 20–50%. Values in this range indicate typical iron transport. Very low saturations (around 0–10%) point to iron deficiency, while very high saturations (above ~60% or into the 70s–90s) suggest iron overload or reduced TIBC. So, the normal range is roughly 20–50%.
