Complete Blood Count (CBC)

The CBC (complete blood count) give us information about the cells which make up the blood stream.

  • White Blood Cells (WBCs): White blood cells are an important part of the immune system. These cells do many things including triggering allergies and fighting off infections. There are five major TYPES of white blood cells (neutrophils, leukocytes, eosinophils, monocytes, and basophils) and each of these cells has a specific job to do. A CBC provides us with a count of these cells and also looks at the structure of these cells. This information helps us to determine whether the immune system is healthy or whether there may be an underlying problem. Conditions such as allergies, asthma, infections, and cancers can trigger abnormalities in the white blood cell count.
  • Red Blood Cells (RBCs): Red blood cells are responsible for delivering oxygen to the tissues and organs throughout the body. A CBC provides us with a count of these cells and also looks at the structure of these cells. Conditions such as dehydration, internal bleeding (tumors, stomach ulcers), chronic kidney disease, bone marrow cancers, autoimmune disorders, and nutritional deficiencies can trigger abnormalities in the red blood cell count.
  • Platelets: Platelets are responsible for forming blood clots which help the body to stop bleeding. A CBC provides us with a count of these cells and also looks at the structure of these cells. Conditions such as internal bleeding (tumors, stomach ulcers, etc), tick-borne diseases (lyme, anaplasma, ehrlichia), bone marrow cancers, autoimmune disorders, and nutritional deficiencies can trigger abnormalities in the platelet count.
