Possible of a 19 year old getting chronic lymphatic leukaemia or any other leukemia? few symptoms plus 'raised lymphocytes' on first blood test

Viral infection: Chronic lymphocytic leukemia is not a disease of teenager. It is commonly in older population of 60 or older. Acute leukemia is more common than chronic leukemia at your age. In addition to increase lymphocytes, other things like low red blood, platelet and presence of symptoms (fever, bony pain, fatigue etc)would be seen. Viral infection is way more common -and it'll also increase lymphocyte count.

Stop worrying: I understand your concern. An elevated percent lymphocytes means nothing without another red flag. An elevation in absolute lymphocytes probably means you are getting a cold. You're too young for cll. If you had acute leukemia or another, the lab would flag the abnormal lymphocytes. If you sense your fear of leukemia is irrational, talk with your physician -- happens to many of us. Good luck.
