Iron

Iron is a mineral that is essential for human health. It plays a crucial role in the production of hemoglobin, a protein in red blood cells that carries oxygen from the lungs to the rest of the body. Iron is also involved in several other important functions in the body, such as immune system function and the regulation of cell growth and differentiation.

Total Iron-Binding Capacity (TIBC) measures the amount of iron-binding sites in the blood. It is used to assess the amount of transferrin, a protein that carries iron in the blood, and to help diagnose iron-related disorders. TIBC is often measured along with other iron tests, such as serum iron and ferritin, to provide a complete picture of an individual's iron status.

Transferrin Saturation measures the amount of iron bound to transferrin in the blood relative to the maximum amount of iron that transferrin can bind. Transferrin is a protein in the blood that binds to and transports iron in the body. Transferrin Saturation is used to assess iron metabolism in the body.

Ferritin is a protein found in the body that stores iron and releases it as needed. It is commonly measured as a biomarker in blood tests to assess iron stores and iron metabolism in the body. Ferritin levels can indicate whether an individual has too much or too little iron stored in the body.
