Total Iron Binding Capacity Normal Ranges
TIBC measures the maximum amount of iron that blood can carry — it reflects the total amount of transferrin available to bind iron.
| Reference Range | Unit | Notes |
|---|---|---|
| 250 – 370 | µg/dL | — |
Also reported in: µmol/L.
Common Causes of High TIBC
Iron deficiency anemia (most common)Pregnancy (increased transferrin production)Oral contraceptive use (estrogen stimulates transferrin synthesis)
Common Causes of Low TIBC
Anemia of chronic disease (liver reduces transferrin production)Iron overload / hemochromatosis (transferrin is saturated)Liver disease (reduced transferrin synthesis)
