You have nothing to worry about.
Our white cell counts are very variable - neutrophil go up if we have a bacterial infection and lymphocytes if we have a viral infection.
Serious conditions ( such as leukemia) of the blood would show up easily on your CBC.
If you are not reassured then have a chat with your own MD to express your concerns.
PS - I observe that your most recent CBC is almost identical to your test in 2004.
PPS - please get back to me if you would like to discuss this some more.
