This test measures ferritin, the primary protein that stores iron in the body.
Diagnostic Value: Ferritin reflects total iron reserves and is one of the most reliable markers for iron deficiency or overload.
Clinical Significance: Low ferritin indicates depleted iron stores; high ferritin may suggest inflammation or hemochromatosis.
Symptom Correlation: Patients may experience fatigue, brittle nails, or pallor.
The Ferritin test is essential for assessing iron balance and storage capacity.
