1. Definition of CBC The Complete Blood Count (CBC) is a blood test commonly used in medical diagnostics. It provides critical information about the types and numbers of cells in the blood, including red blood cells (RBCs), white blood cells (WBCs), hemoglobin, hematocrit, and platelets. This test helps diagnose conditions like anemia, infections, and other blood-related disorders. 2. Principle of CBC The principle of CBC is based on automated blood analyzers, which use laser, electrical impedance, or flow cytometry to measure different blood cell types and properties. Each component, such as RBCs, WBCs, and platelets, is measured by different channels in the machine, where blood cells pass through sensors to determine their count, size, and characteristics.
