Complete Blood Count, and Baselining Your Health


Our lifeblood consists of many components and a complete blood count (CBC) includes measurements of the fundamental elements. The largest categories are red and white blood cells (RBCs and WBCs) and cell fragments called platelets, which play roles in blood clotting. There are 20-30 trillion red blood cells in the body of an adult, each with a lifespan of about 100 days (RBCs contain an iron-containing protein called hemoglobin that enables them to carry oxygen to tissues throughout the body and then return carbon dioxide to the lungs). WBCs are in the front lines in the body’s ongoing fight against harmful viruses, bacteria and even fungus; when a pathogen enters the body, WBCs mobilize in a coordinated defense response to eliminate, neutralize or mark the invader for destruction. The liquid portion of blood is called plasma and it carries nutrients, electrolytes, waste products, and hormones.
