About the TOTAL IRON BINDING CAPACITY (TIBC)
Evaluate iron deficiency/overload.
Sample Required
Blood (venous sample).
Fasting Requirement
As advised by physician.
Why is this Test Done?
- Evaluate iron deficiency/overload.
- Part of iron profile (Iron, TIBC, Transferrin saturation).
General Reference Range
- Serum Iron: ~60–170 µg/dL
- TIBC: ~240–450 µg/dL
- Transferrin Saturation: 20–50%
What Abnormal Results Mean
Low iron with high TIBC suggests deficiency; high iron and saturation suggest overload.
