Hi I am Thejeswar. I am a Medical and Hematooncologist. I can understand your problem. Isolated elevated lymphocyte count can be seen in Viral & bacterial infections (seems less likely) and autoimmune disorders, sometimes stress also can cause a temporary elevation in lymphocyte count. From an oncologist's point of view, we see elevated lymphocyte count in a condition called chronic lymphocytic leukaemia. However, it is associated with elevated WBC count too. Get an evaluation for the above conditions with a good physician. Update me on the status
