One week after a bite is probably too soon to see a big change in white cell counts from Lyme...the body doesn't make enough Lyme antibodies to show up on a test until at least a month after the bite, and I would imagine it would take at least 2-3 weeks before the white cell count would be outside the normal range. However, if they did not look at absolute counts (not just percents) of each type of white blood cell, then subtle differences that may not show up in a total white cell count may have gone unnoticed. I'd encourage you to get a copy of the actual test results so you can discuss what they actually show with your doctor. And sometimes doctors ignore it when a lab value is only slightly out of range, when in actuality it may be significant in particular settings.
I hope this helps - good luck,
