What Does TIBC Stand For?

TIBC stands for Total Iron Binding Capacity

Total Iron Binding Capacity (TIBC) is a medical laboratory test that measures the blood's capacity to bind iron with transferrin, the main protein responsible for iron transport in the body. TIBC helps assess iron metabolism and is commonly used to diagnose conditions related to iron deficiency or overload, such as anemia or hemochromatosis. Elevated TIBC levels typically indicate iron deficiency, while lower levels may suggest iron overload or chronic disease.
