Not enough to worry: The above percentages reflect relative and not absolute values and your actual counts may be borderline normal when calculated from total WBC count. Otherwise in the absence of a clinical context these numbers are uninterpretable. For a better understanding of the trend would suggest using absolute values and not percentages.
