Complete Blood Count (CBC)
A fundamental blood test that counts your red cells, white cells, platelets, and hemoglobin—the cornerstone of many health screenings.

Blood
Measures
White blood cell count (WBC) and differential, red blood cell count (RBC), hemoglobin, hematocrit, RBC indices (MCV, MCH, MCHC), and platelet count.
Identifies
Anemia (iron deficiency, B12, folate), infections (bacterial vs viral clues), bleeding or clotting disorders, leukemia and blood cancers, dengue-related platelet drop, and nutritional deficiencies.
What is the CBC Test?
A Complete Blood Count (CBC) is the most commonly ordered blood test worldwide. It evaluates the three major types of cells in your blood — red blood cells (RBCs) that carry oxygen, white blood cells (WBCs) that fight infection, and platelets that help your blood clot. Think of it as a comprehensive health snapshot — a single tube of blood can reveal anemia, hidden infections, immune disorders, and even early signs of blood cancers.
Why Should You Take This Test?
CBC is the most ordered lab test worldwide. In India, anemia is extremely common (especially in women and children). CBC also helps differentiate dengue (low platelets) from other fevers during monsoon. Essential for routine checkups, fever workup, and pre-surgical clearance.
Who Should Get Tested?
Routine Health Checkup
Everyone above 18 should get a CBC at least once a year.
Women & Children
Anemia is extremely common in Indian women and growing children.
Persistent Fatigue or Weakness
Low hemoglobin or an underlying infection could be the cause.
Fever Lasting 3+ Days
CBC helps distinguish between viral and bacterial infections.
Pre-Surgery Clearance
Surgeons require CBC to ensure adequate blood counts.
Chronic Disease Monitoring
Patients on long-term medications need periodic CBC monitoring.
