Lifestyle factors that can cause a high red blood cell count include: Smoking cigarettes. Living at a high altitude. Taking performance-enhancing drugs such as anabolic steroids (for example, synthetic testosterone) or erythropoietin.

Normally you have between 4,000 and 11,000 WBCs per microliter of blood if you aren’t pregnant. Anything higher is considered leukocytosis. WBC counts between 50,000 and 100,000 per microliter usually mean a very severe infection or cancer somewhere in the body.

Poultry and Lean Meats. Foods high in protein, such as lean meats and poultry, are high in zinc — a mineral that increases the production of white blood cells and T-cells, which fight infection. Other great sources of zinc are oysters, nuts, fortified cereal, and beans.

The CBC can evaluate your overall health and detect a variety of diseases and conditions, such as infections, anemia and leukemia.

A normal platelet count ranges from 150,000 to 450,000 platelets per microliter of blood. Having more than 450,000 platelets is a condition called thrombocytosis; having less than 150,000 is known as thrombocytopenia. You get your platelet number from a routine blood test called a complete blood count (CBC).
