How to Read Your Blood Test Report: Complete Guide for Indians
Learn how to understand every value in your blood test report — CBC, sugar, cholesterol, thyroid, liver, kidney. Simple explanations with normal ranges for Indian adults.
You just collected your blood test report from the lab. It's a page full of numbers, abbreviations like "Hb", "ESR", "SGPT", and columns of values you don't understand. Your doctor appointment is three days away. What do those numbers actually mean?
This guide breaks down every common blood test value — in plain language — so you can understand what's normal, what's concerning, and when to talk to your doctor sooner rather than later.
Complete Blood Count (CBC) — Your Basic Health Snapshot
A CBC is the most commonly ordered blood test in India. It measures the cells that make up your blood and is usually the first test in any health checkup.
Red Blood Cell (RBC) Parameters
| Parameter | Normal (Male) | Normal (Female) | What It Means |
|---|---|---|---|
| Hemoglobin (Hb) | 13.0–17.0 g/dL | 12.0–15.5 g/dL | Oxygen-carrying capacity |
| RBC Count | 4.5–5.5 M/μL | 4.0–5.0 M/μL | Total red blood cells |
| Hematocrit (HCT) | 40–54% | 36–48% | % of blood that is red cells |
| MCV | 80–100 fL | Size of red blood cells | |
| MCH | 27–33 pg | Hemoglobin per red cell | |
| RDW | 11.5–14.5% | Variation in red cell size | |
- Low hemoglobin is extremely common in India — over 50% of Indian women and 25% of men are anemic. Below 12 g/dL (women) or 13 g/dL (men) usually means you need iron or B12 supplements.
- High MCV (above 100) often points to vitamin B12 or folate deficiency — very common in vegetarians.
- Low MCV (below 80) suggests iron deficiency anemia or thalassemia trait, common in certain Indian communities.
White Blood Cell (WBC) Parameters
| Parameter | Normal Range | What It Means |
|---|---|---|
| Total WBC | 4,000–11,000/μL | Your immune system's army |
| Neutrophils | 40–70% | Fight bacterial infections |
| Lymphocytes | 20–40% | Fight viral infections |
| Eosinophils | 1–4% | Fight parasites & allergies |
| Monocytes | 2–8% | Clean up damaged cells |
- High eosinophils are very common in India due to allergies and parasitic infections. If elevated, your doctor may check for worms or allergies.
- Low WBC (below 4,000) can indicate viral infections, bone marrow issues, or certain medications suppressing immunity.
Blood Sugar Tests — Diabetes Screening
India is called the diabetes capital of the world. Understanding these numbers can literally save your life.
| Test | Normal | Prediabetes | Diabetes |
|---|---|---|---|
| Fasting Sugar | 70–100 mg/dL | 100–125 mg/dL | 126+ mg/dL |
| Post-meal (2 hrs) | Below 140 | 140–199 | 200+ |
| HbA1c | Below 5.7% | 5.7–6.4% | 6.5%+ |
| Random Sugar | Below 140 | — | 200+ |
Lipid Profile — Cholesterol & Heart Risk
| Parameter | Desirable | Borderline | High Risk |
|---|---|---|---|
| Total Cholesterol | Below 200 | 200–239 | 240+ |
| LDL (Bad) | Below 100 | 100–159 | 160+ |
| HDL (Good) | Above 40(M)/50(F) | — | Below 40/50 |
| Triglycerides | Below 150 | 150–199 | 200+ |
- Indians have a genetic tendency toward high triglycerides and low HDL — the worst combination for heart health. Even if total cholesterol looks fine, check the breakdown.
- Total/HDL ratio above 5.0 is considered more predictive of heart attack risk than total cholesterol alone.
Thyroid Function Tests
| Parameter | Normal | Hypothyroid | Hyperthyroid |
|---|---|---|---|
| TSH | 0.4–4.0 mIU/L | Above 4.0 | Below 0.4 |
| Free T4 | 0.8–1.8 ng/dL | Below 0.8 | Above 1.8 |
| Free T3 | 2.3–4.2 pg/mL | Below 2.3 | Above 4.2 |
Thyroid disorders affect roughly 1 in 10 Indians, with women 5-8x more likely to be affected. TSH is the screening test — if it's abnormal, your doctor will order T3 and T4 for the complete picture.
Vitamin & Mineral Tests
| Parameter | Normal | India Deficiency Rate |
|---|---|---|
| Vitamin D | 30–100 ng/mL | 70-80% deficient |
| Vitamin B12 | 200–900 pg/mL | Very common in vegetarians |
| Iron (Serum) | 60–170 μg/dL | Common in women |
| Ferritin | 12–150(F) / 12–300(M) | Better iron indicator than serum iron |
