TIBC

The Total Iron-Binding Capacity (TIBC) test measures the maximum amount of iron that can be bound by proteins in the blood, primarily by transferrin, which is the main protein responsible for iron transport. It is part of the iron panel and is used to assess iron metabolism, diagnose iron deficiency anemia, and differentiate between different types of anemia.

Sample type:

Serum

Preparation:

You do not need to do anything special to prepare for the sample collection. Fasting is not required for this test.

Test type:

In person or via trained mobile phlebotomist

Biomarkers

Iron
Transferrin
Total Iron Binding Capacity

Symptoms or conditions analyzed by this test

The TIBC test measures the blood’s capacity to bind iron, providing insight into iron metabolism. Elevated TIBC levels can suggest iron deficiency anemia, with symptoms including fatigue, weakness, and pallor. Reduced TIBC levels may indicate anemia of chronic disease or iron overload conditions like hemochromatosis, with symptoms related to chronic illness or excess iron storage. This test is essential for diagnosing and managing anemia and evaluating iron status.
