What this test is
The TIBC test measures the total amount of iron that can be bound by proteins in your blood, primarily transferrin. It is typically ordered with an iron test to assess iron status and help classify types of anemia.
What it measures
- Total Iron Binding Capacity (TIBC) — reflects the amount of iron that can be bound by transferrin in the blood
- Iron — measures the level of circulating iron in the blood
- Transferrin Saturation — calculated from iron and TIBC, indicates the percentage of transferrin bound with iron
What the test involves
The test requires a standard blood draw from a vein in your arm. The sample is then processed in a laboratory to measure TIBC and iron levels.
Why it is often ordered
A clinician may order a TIBC test to investigate suspected iron deficiency or iron overload, or to help determine the cause of anemia. It is often part of a broader evaluation of iron metabolism.
Preparation
Preparation instructions can vary, so follow the specific directions provided by the collection lab. In some cases, fasting may be required, but always defer to the lab's guidance.
How results are reported
Results are typically reported as a numerical value along with a reference range. Reference ranges can differ between laboratories, so your results should be interpreted in the context of the lab's own range.
