The differential count, the percentages of the main types of white blood cells can suggest a viral versus a bacterial infection, mononucleosis, allergic conditions, and sometimes leukemia. Additional info is gained by looking at the smear under a microscope. Don't forget to check the platelets.

A CBC is often ordered just to see if it is normal. An abnormal CBC rarely can tell you what is wrong, but points you in the right direction so the physician can re-examine the patient, take more extensive history or order further, more specific tests.
