Iron studies refer to a group of laboratory tests that are used to evaluate the body's iron status. These tests typically include measurements of serum iron, total iron-binding capacity (TIBC), unsaturated iron-binding capacity (UIBC), transferrin saturation, and ferritin levels.

Serum iron measures the amount of iron that is circulating in the blood, while TIBC and UIBC measure the body's capacity to bind and transport iron. Transferrin saturation reflects the percentage of transferrin that is bound with iron, and ferritin is a protein that stores iron in the body.

Iron studies are commonly ordered to evaluate conditions such as anemia, iron-deficiency, and iron overload disorders such as hemochromatosis. The results of these tests, in combination with other laboratory tests and clinical findings, can help diagnose and monitor iron-related disorders, as well as guide treatment decisions.

It is important to note that interpreting iron studies requires a healthcare professional to consider other factors such as the patient's medical history, symptoms, and other laboratory tests. A healthcare professional can provide guidance on the appropriate use and interpretation of iron studies.
