A complete blood count is usually part of a routine checkup. A CBC detects anemia, blood cancers, immune system disorders and infections, states the National Heart, Lung and Blood Institute. This blood test measures red blood cells, white blood cells, hemoglobin, hematocrit and platelets. Abnormal results can be an indicator of a medical condition requiring treatment, according to Mayo Clinic.
