causes of low lymphocytes
A: I am sorry, but you do have to be worried about this. Your lymphocyte count is extremely low. There are many potential causes, some of which are serious. Infections are the most common cause. Any serious infection can temporarily reduce lymphocyte count, but most of these are acute, to the point that people need hospitalization. One common infection to cause a low lymphocyte count is HIV. In the early days of the epidemic, a low lymphocyte count was a clue to either acute or advanced HIV.
