"Complete Blood Count"<em> (CBC) </em>is a diagnostic test that is being used in order to check the overall cell counts of the components in a person's blood. Included in these are the<em> Red Blood Cells</em> (RBC), <em>White Blood Cells</em> (WBC), <em>Hemoglobin</em> (Hgb), <em>Hematocrit</em> (hct) and<em> platelets</em>.
If the patient wants to know the number of white blood cells she has, then she needs to undergo a<u> complete blood count test</u>. An increase/decrease in WBC could signal many things like an infection, cancer, bone marrow diseases, etc.
