The protein ferritin serves to store iron. The level of his blood level allows a statement about how much stored iron is present in the body. Read all important information about the laboratory value Ferritin!

What is Ferritin?

Ferritin is a large protein molecule that can store iron. It is the most important iron storage of the body. Each ferritin molecule can store about 4000 iron molecules. The charged with the heavy metal ferritin is located within cells.

The ferritin value is the most important measure to get an impression of the iron metabolism. The ferritin level allows conclusions as to whether the iron stores are empty and the patient has an iron deficiency.

In which cases is ferritin determined?

Ferritin is determined at:

  • Suspected iron deficiency
  • People at risk for iron deficiency such as pregnant women, blood donors, dialysis patients, vegetarians
  • Suspected iron overload (too much iron in the body)
  • Control of therapy with iron supplements

Ferritin is determined in serum or plasma. The following standard values ​​apply to children, adolescents and adults:


0 to 14 days

90 - 628 μg / l

15 days to 2 months

144 - 399 μg / l

3 months

87-430 μg / l

4 to 5 months

37-223 μg / l

6 to 7 months

19 - 142 μg / l

8 to 10 months

14-103 μg / l

11 months to 2 years

1 - 199 μg / l

3 to 15 years

9 - 159 μg / l

16 to 18 years

male: 12-178 μg / l

female: 10 - 163 μg / l

19 to 50 years

male: 9-437 μg / l

female: 9-145 μg / l

from 51 years

male: 9-437 μg / l

female: 17-237 μg / l

The amount of the value depends on the measuring method. The values ​​are therefore only a rough guide.
