Why does my WBC count fluctuate?

Hi,

Welcome to icliniq.com.

Based on your query, my opinion is as follows:

1. WBC - white blood cell count varies in response to infection, inflammation, and various external or internal reactions.
2. A bacterial infection could have increased the WBC count to 80000 with a high neutrophils count.
3. As the count has returned to normal and is only mildly increased, there is nothing to worry about.
4. If there are any immature cells or atypical cells in the blood, then only further evaluation is necessary.
5. Differential leukocyte count is more important than total count. The count will usually vary in response to various conditions, and if increased or persistent then only it is worrisome.
