TIBCug/dL
TIBC estimates how much iron the blood could carry if all transferrin were loaded. It tends to rise when iron is low.

What TIBC measures
TIBC estimates how much iron the blood could carry if all transferrin were loaded. It tends to rise when iron is low.
If your TIBC is low
TIBC below the range is commonly associated with inflammation, liver conditions or iron overload.
Commonly associated with
- Inflammation
- Liver conditions
- Iron overload
- Low protein
If your TIBC is high
TIBC above the range is commonly associated with low iron stores, as the body makes more transferrin to carry iron.
Commonly associated with
- Low iron stores
- Pregnancy
- Estrogen-containing medication
Typical reference range
| Group | Typical range |
|---|---|
| Adults | 250 – 450 ug/dL |
Typical adult values used by many US labs. Your own report prints the range your lab validated for its method, and that range is the one that counts. Labwise always uses the printed range first.
If it is within range
Your TIBC is within the range printed by your lab.
