Your doctor was pretty accurate. The total WBC count is a good indicator about the state of affairs in your blood. Typically, your neutrophil count will always be higher then your lymphocyte count. I'm talking anywhere between 78 - 22 to 65 - 35 neutrophils to lymphs respectively. A count of 92 to 8 would definitely have something going on. If you happen to have the report, look at the absolute numbers instead of the percentages, they will give you better information as far as your real counts.
Neutrophils, or poly-nucleated white cells, are the cells that usually go around and eat up the bacteria, more specifically the eosinophils. An elevated eosinophil count would indicate a bacterial infection.
The lymphocytes, or mono-nucleated white cells, are in a much lower count and do a number of things as well.
The total white cell count will be elevated during an infection or decreased below an absolute number usually indicating something going on that's messing with your white cell production. Stress also has play with your total WBC count, going up during high stress times as you are putting more strain on your body elevating your temperature, releasing hormones or being too tense.
If you're not feeling sick or have something to actually indicate you need another blood test besides a physical, you shouldn't sweat it too much.
