D. complete blood count

Explanation:

"Complete Blood Count" (CBC) 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 Red Blood Cells (RBC), White Blood Cells (WBC), Hemoglobin (Hgb), Hematocrit (hct) and platelets.

If the patient wants to know the number of white blood cells she has, then she needs to undergo a complete blood count test. An increase/decrease in WBC could signal many things like an infection, cancer, bone marrow diseases, etc.
