Complete Blood Count (CBC)

"A complete blood count is a measure of the various cells within the blood. Red blood cells and hemoglobin are responsible for carrying oxygen to the body and carbon dioxide out of the body. The red blood cell count is the absolute number of red blood cells in the blood. A high level can be associated with problems with cardiovascular function, tobacco abuse, stress, high altitude or dehydration. A low count may indicate anemia, or problems with bone marrow or kidney function. 

The complete blood count or "CBC" can be very helpful to assess for the end result of serious nutrient deficiencies. In fact, one of the most common finding of severe iron deficiency is anemia.

White blood cells are part of the immune system and are responsible for fighting off infection. In terms of immune system activation, the white blood count should be within the reference range, unless, of course, there is active infection. There are several types of white blood cells, each with a specific job to do in terms of fighting off threats to the body.

Neutrophils are involved in fighting off bacterial and other infections and are elevated in tissue injury, inflammation, stress, certain metabolic conditions, metastatic cancer and in response to some medications.

Lymphocytes identify foreign substances in the body and produce antibodies against them. Monocytes are increased in response to infection, particularly infection with viral or parasitic agents. They can also be increased in response to chronic infection, inflammatory bowel disease, leukemia and certain cancers.

Eosinophils are typically involved with allergies and parasitic infections. Basophil levels can be elevated in conditions involving inflammation and allergic reactions.

Platelets are involved in the process of blood clotting. When a blood vessel is damaged, platelets clump together and help to initiate clotting. Abnormal platelet counts are found in a number of blood-related and autoimmune diseases."- Dr. Alan Hopkins
