For an explanation of some clinical situations in which this ratio is important, see Total iron-binding capacity.

It is the ratio of serum iron and total iron-binding capacity, multiplied by 100.

This value is called the total iron-binding capacity (TIBC).

Total iron-binding capacity (TIBC) is a medical laboratory test that measures the blood's capacity to bind iron with transferrin.

Total iron-binding capacity (TIBC)

Another lab test saturates the sample to measure the total amount of transferrin; this test is called total iron-binding capacity (TIBC).

The serum iron and total iron-binding capacity (transferrin) are helpful but not diagnostic; it is quiet possible to have co-existing ineffective iron utilisation and iron deficiency, as determined by bone marrow iron status,e.g. in rheumatoid arthritis.

The TIBC is normal to decreased.

See interpretation of TIBC.

High TIBC (total iron binding capacity)

The UIBC is calculated by subtracting the serum iron from the TIBC.

The percent transferrin saturation (i.e., the result of the formula of serum iron/TIBC x 100) can also be a useful indicator.

The Infidel Boat Club (TIBC) is Girton's alumni boat club.

These examples demonstrate that to properly understand a value for TIBC, one also must know the serum iron, the percent transferrin saturation, and the individual clinical situation.
