- Ferritin measures iron stores in the body — it is the most sensitive early marker of iron deficiency
- Serum iron measures iron currently circulating in the blood — it fluctuates throughout the day and with meals
- A complete iron panel (ferritin + serum iron + TIBC + transferrin saturation) provides the most accurate assessment
- Iron deficiency progresses through 3 stages: depleted stores → iron-deficient erythropoiesis → iron deficiency anemia
- Ferritin test costs AED 50-80 in Dubai, while a complete iron panel costs AED 100-200
When investigating iron status, doctors commonly order ferritin and serum iron tests — but they measure very different things. Ferritin reflects your body's iron reserves, while serum iron measures the amount of iron actively circulating in your blood. Understanding the difference is crucial for accurate diagnosis of iron deficiency, iron overload, and related conditions.
Iron deficiency is the most common nutritional deficiency worldwide, affecting an estimated 30% of the global population. In Dubai, it is particularly common among women of reproductive age, vegetarians, and people with chronic conditions. This guide explains each iron test, when to use them, and how to interpret the results.
Ferritin vs Serum Iron: Key Differences
| Feature | Ferritin | Serum Iron |
|---|---|---|
| What it measures | Iron stores in the body | Iron circulating in blood right now |
| Stability | Stable — reflects long-term iron status | Fluctuates with meals, time of day, supplements |
| Best fasting? | Not required (but recommended) | Fasting required for accuracy |
| Normal range (adults) | 20-250 ng/mL (men), 10-120 ng/mL (women) | 60-170 mcg/dL (men), 50-170 mcg/dL (women) |
| Iron deficiency | Low ferritin is the FIRST sign | Drops later, after stores depleted |
| Iron overload | Very high ferritin (>500) | May be elevated |
| Inflammation effect | Falsely elevated (acute phase reactant) | May be falsely low |
| Cost (AED) | 50-80 | 40-60 |
The Complete Iron Panel
| Test | What It Shows | Normal Range |
|---|---|---|
| Ferritin | Iron stores | 20-250 ng/mL (men), 10-120 ng/mL (women) |
| Serum Iron | Circulating iron | 60-170 mcg/dL |
| TIBC (Total Iron Binding Capacity) | Transport protein availability | 250-370 mcg/dL |
| Transferrin Saturation | % of transport protein carrying iron | 20-50% |
| CBC (with MCV, MCH) | Red blood cell size and hemoglobin content | MCV 80-100 fL |
Stages of Iron Deficiency
- Stage 1 — Depleted stores: Ferritin drops below 20-30 ng/mL. Serum iron and CBC still normal. No symptoms yet. Only ferritin detects this stage.
- Stage 2 — Iron-deficient erythropoiesis: Serum iron drops, TIBC rises, transferrin saturation falls below 20%. Red blood cells start becoming smaller (low MCV). Fatigue may begin.
- Stage 3 — Iron deficiency anemia: Hemoglobin drops below normal (anemia). Small, pale red blood cells (microcytic, hypochromic). Clear symptoms: fatigue, weakness, shortness of breath, pallor.
When to Order Which Test
- Screening for deficiency: Ferritin alone is sufficient as the first test
- Confirmed deficiency workup: Full iron panel (ferritin + serum iron + TIBC + transferrin saturation)
- Suspected iron overload: Ferritin + transferrin saturation
- Chronic disease with inflammation: Serum iron + TIBC + transferrin saturation (ferritin may be falsely normal)
- Monitoring iron supplementation: Ferritin recheck after 3 months of treatment

Final Thoughts
Ferritin is the best single test for screening iron status, but a complete iron panel provides the most accurate and comprehensive assessment.
