The Complete Blood Count (CBC) test is a comprehensive blood test that evaluates several important components of the blood, including red blood cells, white blood cells, hemoglobin, hematocrit, and platelets. This test provides valuable information about the overall health of the body and can help diagnose a wide range of conditions, from anemia and infection to certain cancers. The CBC is often used as a part of a routine health checkup to assess an individual's general health status, as well as to monitor conditions and the effectiveness of treatments. Essentially, it’s a crucial snapshot that provides a look into the body’s health and how well its blood components are functioning.
