✅ Normal: 4,000–11,000 /µL
🔺 High = infection, inflammation
🔻 Low = weak immunity
RBC (Red Blood Cells)
👉 Carries oxygen
✅ Normal: 4.5–6.0 million /µL
🔺 High = dehydration
🔻 Low = anemia
Hemoglobin (Hb)
👉 Oxygen-carrying protein
✅ Normal:
Male: 13–17 g/dL
Female: 12–15 g/dL
🔻 Low = anemia
Hematocrit (Hct)
👉 % of RBC in blood
✅ Normal: 37–50%
Platelets (PLT)
👉 Helps clotting
✅ Normal: 150,000–400,000 /µL
🔻 Low = bleeding risk
2. Blood Sugar Test (Glucose Test)
Checks for diabetes.
🔹 Types:
Fasting Blood Sugar (FBS)
✅ Normal: 70–100 mg/dL
Postprandial (PP) (after meal)
✅ Normal: <140 mg/dL
HbA1c (3-month average)
✅ Normal: <5.7%
⚠️ Diabetes: ≥6.5%
3. Lipid Profile (Cholesterol Test)
Checks heart health.
🔹 Components:
Total Cholesterol
✅ <200 mg/dL
LDL (Bad cholesterol)
✅ <100 mg/dL
HDL (Good cholesterol)
✅ >40 mg/dL
Triglycerides
✅ <150 mg/dL
4. Liver Function Test (LFT)
Checks liver health.
🔹 Components:
ALT (SGPT)
✅ 7–56 U/L
AST (SGOT)
✅ 10–40 U/L
ALP
✅ 44–147 U/L
Bilirubin
✅ 0.1–1.2 mg/dL
🔺 High = jaundice
5. Kidney Function Test (KFT / RFT)
Checks kidney function.
🔹 Components:
Creatinine
✅ 0.6–1.3 mg/dL
Blood Urea (BUN)
✅ 7–20 mg/dL
eGFR
✅ >60 (normal kidney function)
6. Electrolyte Test
Checks body balance.
🔹 Components:
Sodium (Na) → 135–145 mmol/L
Potassium (K) → 3.5–5.0 mmol/L
Chloride (Cl) → 96–106 mmol/L
7. Thyroid Function Test (TFT)
Checks thyroid gland.
🔹 Components:
TSH → 0.4–4.0 mIU/L
T3 & T4 → Hormone levels
🔺 High TSH = Hypothyroidism
🔻 Low TSH = Hyperthyroidism
8. Vitamin Tests
Vitamin D → 20–50 ng/mL
Vitamin B12 → 200–900 pg/mL
9. Infection Tests
HIV Test
Hepatitis B & C
Dengue / Malaria tests
10. Coagulation Test
Checks blood clotting:
PT (Prothrombin Time)
INR
⚠️ Important Notes:
Normal ranges may vary by lab
Always consult a doctor for interpretation
One abnormal value ≠ disease (needs clinical correlation)
