Iron levels in the body are measured by both hemoglobin and serum ferritin blood tests.
Routine tests with high ferritin levels can be an indication of an iron storage disorder. One such disorder is hemochromatosis. This is a genetic disorder that results in iron-overload in the body.
iron level tests, total iron-binding capacity (TIBC) tests, ferritin tests, and transferrin tests.

Typically, measuring the blood iron content would be an iron level. TIBC (total iron binding capacity), transferrin, and ferritin are related tests that are sometimes done when iron levels are in question.
A ferreting blood test tests for the levels of ferreting in the blood. Ferreting is an iron storing protein, and high levels of this protein can be indicative of an iron storing disorder in the body.
Ferritin is a protein that stores iron and releases it in a controlled fashion. Hence, the body has a "buffer" against iron deficiency (if the blood has too little iron, ferritin can release more) and, to a lesser extent, iron overload (if the blood and tissues of the body have too much iron, ferritin can help to store the excess iron).
