The iron profile test is a series of blood tests that evaluate the body's iron levels and its ability to use it. The test provides information about the various components of iron in the blood, including:
- Serum Iron: Measures the amount of iron in the blood, which is bound to transferrin protein.
- Total Iron-Binding Capacity (TIBC): Measures the amount of transferrin in the blood available to bind to iron.
- Transferrin Saturation: It is calculated by dividing the serum iron by the TIBC, and it indicates the percentage of transferrin that is saturated with iron.
