About this biomarker
TIBC estimates how much iron transferrin can carry in the blood. It is usually interpreted with serum iron and ferritin.
Why it matters
It adds context in iron deficiency and other iron-balance patterns.
What lower levels may suggest
Low TIBC may be seen with inflammation, liver disease, malnutrition, or iron overload.
What higher levels may suggest
High TIBC may be seen with low iron stores or increased transferrin production.
Common tests
