Total Iron Binding Capacity (TIBC)
Vitamins & Minerals blood
What It Is
TIBC measures the blood's capacity to bind iron with transferrin, reflecting iron transport ability.
Why It Matters
TIBC helps distinguish between different causes of anaemia and iron disorders.
If Levels Are High
High TIBC indicates iron deficiency, as the body increases transferrin to capture more iron.
If Levels Are Low
Low TIBC may indicate iron overload, chronic disease, or malnutrition.
Preparation
Morning fasting sample preferred.
How Often to Test
As clinically indicated alongside iron studies.
