I have a slightly high lymphocytes count at 41%, what does that mean? and should i be concerned?

Need more info: Lymphocyte count of 41% per se is no reason to worry. What is you total white blood cell count?

Means nothing: Percentages fluctuate wildly even hour by hour. The only numbers that are really concerning is if the absolute neutrohil or absolute lymphocyte count is far from the reference range. You know that reference ranges are set so that several percent of healthies fall outside on either end. Be thankful for good health.
