What is this test?
Ferritin is a protein that reflects the body's iron stores. Low ferritin usually indicates depleted iron stores, i.e. iron deficiency; high ferritin may be seen with iron overload, inflammation or liver disease. When investigating the cause of anemia, it is evaluated together with serum iron and iron-binding capacity.
When is it requested?
Differential diagnosis of iron deficiency anemia, iron overload, iron malabsorption
What does a high Ferritin result mean?
High ferritin does not always mean too much iron; ferritin is also a protein that rises during inflammation and infection.
- Infection, inflammation or a recent illness
- Fatty liver, excess weight and metabolic syndrome
- Regular alcohol use
- Iron supplements taken too long or at high doses, frequent blood transfusions
- Liver diseases such as hepatitis
- Inherited iron overload disorder (hemochromatosis)
- Less commonly, certain rheumatic diseases or cancers
What does a low Ferritin result mean?
Low ferritin means your body's iron stores are depleted and is one of the most reliable signs of iron deficiency; it can drop even before anemia develops.
- Heavy or prolonged menstrual periods
- Increased iron needs during pregnancy and breastfeeding
- Low-iron diet, vegetarian or vegan eating
- Frequent blood donation
- Rapid growth in children and teenagers
- Absorption problems such as celiac disease, or after stomach surgery
- Unnoticed blood loss from the digestive tract
My result is outside the reference range. What should I do?
Because ferritin can look normal during inflammation, it is interpreted together with serum iron, iron-binding capacity and sometimes CRP. Don't start iron supplements on your own; review the result with your doctor.
Reference ranges depend on the method, age and sex; always use the range printed on your report. This information is for general guidance only; consult your doctor for diagnosis and treatment.
