Serum Ferritin

Iron is an essential mineral required for various bodily functions, including oxygen transport, energy production, and enzyme activity. It is also vital for healthy muscles, bone marrow, and other functions, including brain development in children. Ferritin, primarily concentrated in the liver and immune system cells, is responsible for storing excess iron safely. When the body needs iron, ferritin releases it into the blood for use.

The Serum Ferritin test helps detect diseases such as iron deficiency anemia, a condition characterized by low levels of iron in the body, hemochromatosis (iron overload), which can lead to organ damage (particularly the liver), and the nutritional status of an individual (concerning iron intake). It also helps monitor iron levels in individuals with chronic diseases or those receiving iron therapy.

Your doctor may advise the Serum Ferritin test when you have symptoms suggestive of altered iron levels, such as pale skin, extreme tiredness, weakness, heavy menstrual cycles, bleeding in your digestive tract, blood in your stool, shortness of breath, brittle nails, whooshing sound in your ears, and sudden spinning sensations (vertigo). 

No special preparation is needed for a ferritin test; eat or drink as per your daily routine. However, talk to your doctor about all the pre-test instructions. 

Test result ranges are approximate and may differ slightly between labs depending on the methodology and laboratory guidelines. Talk to your doctor about your specific test results. The test results will help them develop appropriate management plans based on your needs and circumstances.
