Your total white cell count of 7000 is normal, and that matters more here than the percentages. Neutrophils and lymphocytes are usually reported as a percentage of the total, so a drop in one naturally raises the other even when both are fine in absolute numbers.
Next Steps
Your absolute neutrophil and lymphocyte counts are both within range here, so the percentage shift looks relative rather than a real abnormality. This pattern is common for a few weeks after recovering from an infection, as counts gradually settle back.
Health Tips
Absolute counts are generally the more reliable number to follow, but please consult your physician to confirm this specific reading against your full history.
