The Ferritin Test, also known as the Serum Ferritin Test, is a medical test that measures the level of ferritin in the blood. Ferritin is a protein that stores iron in the body and releases it when needed. The test is used to diagnose and monitor conditions related to iron metabolism, such as iron deficiency anemia and hemochromatosis. The ferritin test is a simple blood test that can be done in a laboratory or doctor's office. During the test, a healthcare professional uses a needle to draw a small sample of blood from a vein in your arm. The sample is then sent to a laboratory for analysis. Results are usually available within a few days and can help your healthcare provider determine if you have an iron-related condition that requires treatment.

Purpose of the test

The Ferritin Test is a valuable tool for diagnosing and managing various conditions related to iron metabolism. The test measures the level of ferritin in the blood, which reflects the total amount of iron stored in the body. Here are some of the goals of the ferritin test

- Diagnose iron deficiency anemia: Iron deficiency anemia is a common condition that occurs when there is not enough iron in the body to produce hemoglobin, a protein in red blood cells that carries oxygen. The ferritin test can help diagnose iron deficiency anemia by measuring the level of ferritin, which is low in people with this condition.

- Diagnosing hemochromatosis: Hemochromatosis is a genetic disorder that causes the body to absorb too much iron, resulting in iron overload. The ferritin test can help diagnose hemochromatosis by measuring the level of ferritin, which is high in people with this condition.

- Monitoring treatment of iron-related conditions: The ferritin test can be used to monitor treatment for conditions such as iron deficiency anemia and hemochromatosis. For example, if you are being treated for iron deficiency anemia, your healthcare provider may order regular ferritin tests to monitor your response to treatment.

- Assessing overall health: The ferritin test may also be used as part of a routine physical exam to assess general health. Low ferritin levels may indicate anemia or other health problems, while high levels may indicate inflammation or liver disease.

Recognizing and treating iron-related conditions early can prevent serious complications such as organ damage and heart failure. If left untreated, these conditions can lead to life-threatening complications. Therefore, it is important to have a ferritin test if you have symptoms such as fatigue, weakness, or shortness of breath that may be related to anemia, or if you have a family history of hemochromatosis. In addition, routine ferritin testing can help detect iron-related conditions before they cause symptoms, allowing for early intervention and treatment.

Who Should Get Tested

The Ferritin Test is indicated for people who are at risk for iron-related disorders or who have symptoms that may be related to anemia. Here are some groups of people who may need to be tested:

- People with a family history of hemochromatosis: Hemochromatosis is a genetic disorder that causes iron overload in the body. If you have a family history of hemochromatosis, your healthcare provider may recommend regular ferritin testing to monitor your iron levels.

- People with symptoms of anemia: Anemia is a condition that occurs when there is not enough hemoglobin in the blood to carry oxygen to the body's tissues. Symptoms of anemia include tiredness, weakness, shortness of breath, and pale skin. If you have these symptoms, your healthcare provider may order a ferritin test to check for iron deficiency anemia.

- Women with heavy menstrual bleeding Women who have heavy menstrual bleeding are at risk for iron deficiency anemia due to blood loss. If you have heavy menstrual bleeding, your healthcare provider may recommend regular ferritin testing to monitor your iron levels.

- Pregnant women: Pregnant women need more iron than usual to support the growth and development of their baby. If you are pregnant, your healthcare provider may order a ferritin test as part of your routine prenatal care.

- People with inflammatory bowel disease or who have had gastrointestinal surgery: These conditions can interfere with the absorption of nutrients from food, including iron. If you have inflammatory bowel disease or have had gastrointestinal surgery, your healthcare provider may recommend regular ferritin testing to monitor your iron levels.

If you are at risk for an iron-related condition or have symptoms that may be related to anemia, it is important to talk with your healthcare provider about whether ferritin testing is right for you.

Blood Test Preparation Guidelines
Time of day
icon
It is recommended to schedule your appointment for blood tests in the morning hours between 7:00-10:00.
Fasting
icon
It is recommended to fast for approximately 12 hours before blood sampling. The last meal of the previous day should ideally be consumed around 6:00 p.m. On the day before the test, avoid heavy and fatty meals as well as alcohol.
Stay hydrated
icon
Drinking water prior to testing can help with sample collection.
Other factors
icon
Tests should not be performed after a sleepless night or intense physical activity. It is recommended to avoid exercise and stress immediately before blood collection and to not smoke. A short rest is recommended.
Medications and supplements:
icon
Blood samples should be collected before the morning dose. Some drugs can interfere with test results. Consult with your doctor whether you can delay your dose because of lab tests.
Biotin supplements:

High doses of biotin supplements can affect test results, causing false elevation or reduction. It's recommended to avoid taking biotin for at least 72 hours before blood collection. If you are taking biotin, inform the personnel collecting the blood so that they can provide specific instructions.
Interpreting Test Results

Ferritin test results are interpreted by comparing the patient's ferritin level to a reference range. The reference range is based on age, gender, and overall health. Here are some general guidelines for interpreting ferritin test results:

- Low ferritin levels: Low ferritin levels may indicate iron deficiency anemia or other health problems. The normal range for ferritin levels varies by age and sex, but generally a level below 12 ng/mL in women and below 30 ng/mL in men is considered low.

- Normal ferritin levels: Normal ferritin levels vary with age and gender, but generally fall in the range of 12-150 ng/mL for women and 30-400 ng/mL for men.

- High ferritin levels: High ferritin levels may indicate hemochromatosis or other health problems. The normal range for ferritin levels varies by age and sex, but generally a level above 150 ng/mL in women and above 400 ng/mL in men is considered high.

Ferritin test results should be interpreted in conjunction with other tests and clinical findings to make an accurate diagnosis. Your healthcare provider will use your Ferritin test results along with your medical history, physical exam, and other tests to determine if further testing or treatment is needed. If you have questions about your Ferritin test results or what they mean for your health, be sure to discuss them with your healthcare provider.
