Ferritin
- Sample Type
- Standard
- Fasting
- No
- Unit
- ng/mL
Ferritin is the primary intracellular iron-storage protein and reflects total body iron stores. It is the most sensitive and specific marker for iron deficiency. However, it also acts as an acute-phase reactant, meaning its concentration increases during systemic inflammation, regardless of iron status.

Why Context Matters
Ferritin levels can be falsely elevated by inflammation, liver disease, or malignancy, potentially masking a concurrent iron deficiency.
Lab ranges are statistical averages, not biological laws. "Normal" for a 20-year-old male isn't normal for a 60-year-old female.
