Yes, that seems very low. Lymphocytopenia is a count of lymphocytes below 1500, so you are unusually low. The lymphocytes help fight off bacteria, viruses and fungi. The most important thing for you isn't the low number of lymphocytes, but rather what is causing them to be low. There are diseases that cause Lymphocytopenia are cancer, rheumatoid arthritis, lupus, chronic infections, AIDS and some other viral infections. Your doctor will have to find out your cause and treat it. I would keep pressing the doctor about this until you are satisfied.
