About Our Ferritin Test

Note: Fasting is not required for this test.

Ferritin is found in virtually all cells of the body and serves as the cellular storage repository for iron. The majority of ferritin iron stores are found in the liver, spleen and bone marrow. This test is used to measure ferritin levels in the blood.

Ferritin is present in small concentrations that correlate with total-body iron stores, making its measurement valuable for the assessment of disorders relating to iron metabolism. Ferritin fluctuates with iron levels; when iron levels are low, so are ferritin levels, which can cause symptoms of weakness, fatigue and dizziness. When there is an abundance of iron, there is an increase in ferritin, which can cause swelling of the liver and liver damage, fatigue, weight loss, weakness and sometimes darkening of the skin.

Low levels of Ferritin can be found when iron stores are exhausted, well before the serum iron level has become affected. In cases of anemia, low serum Ferritin is often a very specific indicator for iron-deficiency anemia.
