Total Iron Binding Capacity (TIBC) is an approximation of Transferrin. A mathematical relationship between TIBC and transferrin can be derived. When an Iron and TIBC are ordered together, then an Iron and a Transferrin are both analyzed and the TIBC is calculated using the following calculation:
TIBC (μg/dL) = Transferrin (mg/dL) X 1.4
Clinical Significance
Serum iron (IRON), total iron-binding capacity (FETIBC), and/or transferrin tests are usually ordered together to assess how much iron is being carried in the blood. A ferritin test may also be used to evaluate a person's current iron stores.
These tests are used together to detect and help diagnose iron deficiency or iron overload. In people with anemia, these tests can help determine whether the condition is due to iron deficiency or another cause, such as chronic blood loss or some other illness. Iron tests are also ordered if a doctor suspects that a person has iron poisoning and to screen for hereditary hemochromatosis, an inherited condition associated with excessive iron storage.
