Iron Deficiency Anaemia: How to Read Your Iron Panel Report

India has one of the highest rates of iron deficiency anaemia in the world. According to the National Family Health Survey, more than half of women and children in India are anaemic. Yet most people who get flagged on their blood test have no idea what the numbers mean — or what to do next.

This guide breaks down the full iron panel in plain language.

What Is Iron Deficiency Anaemia?

Anaemia means your blood doesn't have enough healthy red blood cells to carry oxygen efficiently to your organs and tissues. Iron deficiency is the most common cause — your body needs iron to make haemoglobin, the protein inside red blood cells that carries oxygen.

You can have iron deficiency without anaemia (low iron stores, but haemoglobin still normal), or full-blown iron deficiency anaemia (low iron stores AND low haemoglobin). The iron panel helps distinguish exactly where you are on this spectrum.

The Parameters — One by One

Haemoglobin (Hb)

Normal range (Indian adults):

Men: 13.0–17.0 g/dL
Women: 12.0–15.0 g/dL
Pregnant women: ≥ 11.0 g/dL (WHO threshold)
Children 6–12 years: ≥ 11.5 g/dL

Haemoglobin is the most direct measure of anaemia. It tells you how much oxygen-carrying protein is in your blood right now.

Severity classification (WHO):

Mild anaemia: 10–12 g/dL (women) / 10–13 g/dL (men)
Moderate anaemia: 7–10 g/dL
Severe anaemia: below 7 g/dL

Serum Ferritin

Normal range:

Men: 24–336 ng/mL
Women (pre-menopausal): 11–307 ng/mL
Women (post-menopausal): 14–186 ng/mL

Ferritin is the storage form of iron in your body. Think of it as the iron "warehouse." It's the earliest indicator of iron deficiency — your ferritin drops before your haemoglobin does.

This is the most important single marker in an iron deficiency workup.

A ferritin below 30 ng/mL is considered iron depleted even if haemoglobin is still normal. Many people with chronic fatigue, hair loss, and poor concentration have low-normal haemoglobin but very low ferritin — and feel dramatically better once ferritin is replenished.

Important caveat: ferritin is also an acute-phase reactant — it rises during infections, inflammation, and liver disease regardless of iron status. So a "normal" ferritin during an illness doesn't rule out iron deficiency.

Serum Iron

Normal range:

Men: 65–175 μg/dL
Women: 50–170 μg/dL

Serum iron measures the iron currently circulating in your blood, bound to a protein called transferrin. It fluctuates significantly throughout the day (highest in the morning, lower in the evening) and can be affected by a single iron-rich meal. This makes it less reliable on its own — it's most useful when interpreted alongside TIBC and ferritin.

TIBC — Total Iron Binding Capacity

Normal range: 250–370 μg/dL

TIBC measures your blood's total capacity to carry iron — essentially how many "seats" are available on transferrin proteins for iron to bind to. When your iron stores are low, your body makes more transferrin to capture every bit of iron available — so TIBC goes up when iron is deficient.

The classic iron deficiency pattern:

Serum iron: LOW
TIBC: HIGH (your body is "reaching out" for more iron)
Ferritin: LOW (the warehouse is empty)

Transferrin Saturation (%)

Normal range: 20–50%

Transferrin saturation = (Serum Iron ÷ TIBC) × 100

This tells you what percentage of your blood's iron-carrying capacity is actually filled. In iron deficiency, this percentage drops because you have low iron but high capacity.

A transferrin saturation below 16% is a strong indicator of iron-deficient erythropoiesis (your bone marrow is struggling to make red blood cells due to insufficient iron).

MCV — Mean Corpuscular Volume (from CBC)

Normal range: 80–100 fL

MCV measures the average size of your red blood cells. In iron deficiency anaemia, red blood cells become smaller than normal — a condition called microcytic anaemia (MCV < 80 fL). This is because without enough iron, your body can't make full-sized red blood cells.

The Classic Iron Deficiency Pattern at a Glance

| Marker | Iron Deficiency | Normal | |---|---|---| | Haemoglobin | Low (or borderline) | Normal | | Ferritin | Low (< 30 ng/mL) | Normal | | Serum Iron | Low | Normal | | TIBC | High | Normal | | Transferrin Saturation | Low (< 16%) | Normal | | MCV | Low (< 80 fL) | 80–100 fL |

Who's Most at Risk in India?

Iron deficiency is not equally distributed. You're at higher risk if you:

Are a woman of reproductive age — menstruation causes regular iron loss, and many Indian diets don't replenish it adequately
Are pregnant or recently delivered — iron demand is significantly higher during pregnancy
Are vegetarian or vegan — plant-based iron (non-haem iron) is absorbed far less efficiently than animal-based iron (haem iron)
Have heavy periods — even if periods seem "normal" by your own measure, heavy flow can cause gradual depletion
Eat a diet high in tea/coffee with meals — tannins in tea drastically reduce iron absorption when consumed with food
Have a gut condition — celiac disease, IBS, or gut inflammation can impair iron absorption
Are a child or adolescent — rapid growth increases iron demand

Foods That Help and Hurt Iron Absorption

Iron-rich foods (non-haem, absorbed at ~5–10%):

Bajra, ragi, poha
Spinach, methi, drumstick leaves
Rajma, chana, masoor dal
Dates, jaggery, dried figs

Foods that boost absorption:

Vitamin C alongside iron-rich meals — lemon juice squeezed on dal, amla, tomatoes. This can increase non-haem iron absorption by 2–3x.

Foods that reduce absorption:

Tea and coffee within 1 hour of meals (tannins)
Calcium-rich foods at the same time (milk, curd)
Phytates in whole grains (this is why soaking and sprouting helps)

Questions to Ask Your Doctor

If your iron panel is flagged, ask:

Do I need iron supplementation, and if so, what dose and for how long?
Is my ferritin low enough to explain my symptoms (fatigue, hair loss)?
Should we investigate why my iron is low — is there blood loss or absorption issue?
Are there any dietary changes that would make the biggest difference?
When should I retest to check if the treatment is working?

The Takeaway

Iron deficiency is one of the most common and most underdiagnosed conditions in India — especially in women and children. The good news: it's one of the most correctable too. The key is not just looking at haemoglobin, but also at ferritin, which often falls well before haemoglobin does. If you're chronically tired, losing hair, or struggling to concentrate, a full iron panel (not just a CBC) is worth asking for.
