Ferritin is a protein that stores iron in the body. A ferritin test measures the level of ferritin in the blood. It is a useful test for evaluating iron stores, and for evaluating and monitoring iron-deficiency anemia or other types of anemia.

Pre-test preparation: No special preparation is typically required for a ferritin test. However, it is important to inform your healthcare provider of any medications you are currently taking, as some medications may affect the test results.

Testing method: A small sample of blood is taken from a vein in the arm and sent to a laboratory for analysis. The sample is usually analyzed using a device called an immunoassay analyzer.

Common symptoms for prescribing this test: A ferritin test may be ordered if a person has symptoms of anemia, such as fatigue, weakness, or pale skin. It may also be ordered if a person has a history of iron-deficiency anemia, or if a person has a condition that increases the risk of iron-deficiency anemia, such as heavy menstrual periods or gastrointestinal bleeding.

Diagnosis: The results of a ferritin test are used to help diagnose and monitor a variety of conditions, including iron-deficiency anemia, chronic disease, and certain types of cancer. Elevated levels of ferritin can indicate the presence of inflammation, liver disease or certain types of cancer, while low levels can indicate iron-deficiency anemia or other types of anemia.

Reference range: The reference range for ferritin levels varies depending on the lab and the population being tested, but generally, for men it is 30-400 ng/mL and for women it is 12-150 ng/mL. However, it can vary based on age, sex and other factors.

Normal values: Ferritin levels are normally between 30-400 ng/mL for men and 12-150 ng/mL for women.
