Complete Blood Count (CBC)

A Complete Blood Count (CBC) is one of the most essential diagnostic tools because it provides a comprehensive snapshot of your overall health by measuring 21 different components of your blood. It is incredibly helpful for detecting a wide range of conditions—from common issues like anemia and infections to more serious disorders like leukemia or immune system suppressed states. By evaluating your red blood cells (which carry oxygen), white blood cells (which fight off invaders), and platelets (which help with clotting), this test allows your doctor to pinpoint the cause of symptoms like fatigue, bruising, or fever, and can even catch underlying health shifts before you feel any symptoms at all.
