Ferritin (Ferr)




Ferritin is an iron-containing protein. This test can determine your body’s total iron storage capacity.

In the early stages of iron-deficiency, blood levels of iron can be normal while stored iron (ferritin levels) will begin to decrease. A ferritin level may also be ordered when iron overload is suspected.

In the early stage of iron deficiency, no physical effects are usually seen. If a person is otherwise healthy, symptoms seldom appear before the hemoglobin in the blood drops below a certain level (10 g per deciliter). However, as the iron-deficiency progresses, symptoms eventually begin to develop and a doctor may order ferritin as well as other iron-related tests. The most common symptoms of iron deficiency anemia include:

  • Chronic fatigue/tiredness
  • Weakness
  • Dizziness
  • Headaches
  • Pale skin (pallor)

Fasting Required: You may be instructed to fast for 12 hours before the test; in this case, only water is permitted.
