Doctor's Assessment Included
Every result includes a professional assessment from a BIG-registered doctor. For treatment decisions, discuss your results with your GP.
Transferrin
TIBC reveals your blood's capacity to transport iron, a key factor for energy and oxygen delivery. It helps complete the picture of your iron metabolism.
What It Measures
This test measures the total amount of iron that transferrin in your blood can carry. It is typically used alongside serum iron and ferritin to evaluate iron status.
Why It Matters
TIBC helps distinguish between different causes of anaemia and iron imbalances. High TIBC often suggests iron deficiency, while low TIBC may be associated with iron overload or chronic disease. Consult your healthcare provider for interpretation.
When to Test
TIBC is usually ordered as part of an iron studies panel when investigating anaemia, fatigue, or suspected iron deficiency or overload.
Symptoms
Low Levels
Low TIBC may be associated with iron overload conditions, liver disease, chronic inflammation, or malnutrition. Symptoms depend on the underlying cause.
High Levels
High TIBC is often seen with iron deficiency and may be associated with symptoms such as fatigue, pale skin, weakness, and shortness of breath.
Lifestyle Tips
If TIBC is elevated due to iron deficiency, focus on iron-rich foods paired with vitamin C. If low due to iron overload, your healthcare provider will guide dietary modifications and treatment.
Frequently Asked Questions
What does a high TIBC mean?
A high TIBC typically indicates that your body is trying to bind more iron because stores are low. It is often seen in iron deficiency. Your healthcare provider can confirm the diagnosis.
How is TIBC different from transferrin?
TIBC measures the total iron-binding capacity of transferrin, while transferrin is the actual protein. TIBC is an indirect measurement of transferrin function.
Should TIBC be tested alone?
TIBC is most useful when interpreted alongside serum iron, ferritin, and transferrin saturation for a comprehensive iron status assessment.
