Serum Iron
- Sample Type
- Standard
- Fasting
- No
- Unit
- µg/dL
This test measures the amount of circulating iron that is bound to the transport protein transferrin. In the context of an Iron Deficiency Profile, it must be interpreted alongside Ferritin and TIBC. Iron is essential for hemoglobin synthesis; low levels lead to microcytic anemia, while excess levels can lead to organ damage (hemosiderosis).

Why Context Matters
Serum iron has high diurnal variation (levels are peak in the morning and drop at night) and is highly influenced by recent dietary intake or iron supplements. A single low reading may not accurately reflect total body iron stores.
Lab ranges are statistical averages, not biological laws. "Normal" for a 20-year-old male isn't normal for a 60-year-old female.
