FERRI | Ferritin

Ferritin is a protein that stores iron in the body and reflects the amount of iron reserves. It is one of the most accurate laboratory indicators for detecting iron deficiency even before obvious anemia manifests. The ferritin test is crucial in assessing iron metabolism, especially if hemoglobin levels are decreased or chronic anemia is suspected.

Ferritin concentration in the blood decreases with iron deficiency, often due to improper nutrition, chronic bleeding, or digestive tract disorders. However, it is important to know that ferritin levels can also increase regardless of iron excess, which is common in inflammatory processes, liver dysfunction, or cancerous diseases.

Test principle: Ferritin concentration is determined by an immunochemical method from venous blood. Results are presented in ng/ml or µg/l units. It is often assessed together with hemoglobin, iron, transferrin, or TIBC tests.

Recommendations:

• It is recommended to perform prophylactically once a year.
• Useful in suspected iron deficiency or anemia.
• The test is performed when hemoglobin is decreased or constant fatigue is present.
• Prescribed to evaluate the effectiveness of iron supplement treatment.
• Ferritin levels can be affected by inflammation, infections, chronic diseases, or medications.
• No specific preparation is required for the test, but it is recommended to perform it in the morning on an empty stomach.
