Total iron binding capacity
.Total Iron Binding Capacity
Total Iron Binding Capacity (TIBC) is a blood test that measures the total amount of iron-binding proteins which binds to iron in a person's blood. It is primarily used to evaluate the amount of iron available in a person's system, although it can also be used as part of a screening for hemochromatosis.
Preparation
No special preparation is required for TIBC test. Your doctor will simply draw a sample of your blood, which will be sent to the laboratory for analysis.
Procedure
TIBC testing is performed on a blood sample.
- A small sample of your blood will be taken using a needle
- The blood sample will be sent to a laboratory for measurement of the TIBC
- The results of the TIBC test will be reported back to your doctor
Types
There are two types of TIBC tests:
- Unsaturated TIBC: Measures the amount of transferrin that is available to bind to iron in the blood.
- Saturated TIBC: Measures the amount of transferrin that is already bound to iron in the blood.
Risks
TIBC testing is a low-risk test and poses little to no risk. The most common risks associated with TIBC testing include discomfort or bruising at the injection site.
Why
TIBC testing is done to evaluate the amount of iron available in a person's blood. It is used to detect and diagnose iron deficiency anemia, as well as other forms of anemia such as vitamin B12 deficiency.
When
TIBC testing is typically done along with a complete blood count (CBC) and other tests to evaluate iron levels in the body. It is often done as part of a screening for anemia, hemochromatosis, or other iron-related disorders.
Normal Values
Normal TIBC levels are typically between 250–450 µg/dL.
