Ferritin Test

The ferritin test is a blood test used to measure the level of ferritin in the body. Ferritin is a protein that stores iron, and the test is often used to assess iron deficiency or overload.

What is Ferritin?

Ferritin is a protein found in the body that plays a crucial role in storing and releasing iron. It acts as a buffer, helping to regulate the amount of iron available for various bodily functions, such as the production of red blood cells.

Purpose of the Test

The ferritin test is used to:

• Diagnose and monitor iron deficiency anemia
• Assess iron overload or hemochromatosis
• Evaluate the effectiveness of iron supplementation therapy
• Monitor individuals with chronic diseases, such as kidney disease or rheumatoid arthritis, who may be at risk for iron deficiency or overload

How the Test is Performed

A healthcare professional will draw a blood sample from a vein in the arm using a needle and syringe. The blood sample is then sent to a laboratory for analysis.

Interpretation of Results

The results of the ferritin test are typically reported in nanograms per milliliter (ng/mL) or micrograms per liter (μg/L). The normal range for ferritin levels varies depending on factors such as age, sex, and laboratory methods. Generally:

• Normal ferritin levels: 15-300 ng/mL (male), 10-200 ng/mL (female)
• Low ferritin levels: may indicate iron deficiency anemia
• High ferritin levels: may indicate iron overload, hemochromatosis, or other conditions such as inflammation or liver disease

Risks and Limitations

The ferritin test is a relatively safe procedure with minimal risks. However, it may not be suitable for individuals with certain medical conditions, such as those with severe kidney or liver disease. Additionally, the test may not provide accurate results in cases of acute inflammation or recent blood transfusions.

Preparation and Aftercare

No special preparation is typically required for a ferritin test. Individuals should follow their healthcare provider's instructions regarding any medications or supplements that may need to be stopped before the test. After the test, individuals can resume their normal activities, and results are usually available within a few days.
