Ferritin
From WikiLectures
"Ferritin" is a storage protein containing iron, which is found mainly in the liver, spleen, bone marrow and intestinal mucosa. A small proportion is released into the bloodstream. The level of ferritin in the blood serum reflects the tissue stores of iron. Its value decreases before the level of transferrin u increases. [1]
It is a complex consisting of the protein apoferritin em and the ferric iron Fe 3+ . [2]
Normal values of ferritin[edit | edit source]
- Males: 22 - 322 μg / l
- Women: 10 - 291 μg / l [3]
High Iron level[edit | edit source]
- Hemochromatosis,
- Wilson's disease,
- Blood transfusion,
- Excessive iron intake in the diet,
- Porphyria cutanea tarda,
- Ineffective erythropoiesis (sideroblastic anemia, thalassemia).
Inflammation[edit | edit source]
Ferritin is one of the acute phase reactants
- Rheumatoid arthritis,
- SLE,
- non-specific intestinal inflammation,
- bacterial infections;
Liver disease[edit | edit source]
Ferritin is stored mainly in hepatocytes, when they are damaged it is released into the blood.
- liver steatosis (NASH),
- viral hepatitis B, C;
Other causes[edit | edit source]
Obesity, alcohol abuse, thyrotoxicosis and malignancies, especially haematological [4] Rarely, extremely high levels of ferritin can be a symptom of histiocytosis or Still's disease. [5]
