The Complete Blood Count (CBC) test is a routine blood examination that evaluates the three major components of your blood—red blood cells, white blood cells, and platelets. It helps detect conditions such as infections, anemia, inflammation, immune system disorders, and various blood-related diseases. The test measures key parameters including hemoglobin, hematocrit, RBC count, WBC count, differential counts, platelet count, and other important indices. No fasting is required for this test, and a small blood sample is collected from a vein using an EDTA tube.
