What is lymphocytopenia

Lymphocytes are a kind of white blood cell. They’re part of your immune system. These essential cells circulate in blood and lymph fluid. They defend your body by attacking at the first sign of an invasion by harmful organisms. Lymphocytes also play a key role in triggering other immune actions and help in building your body’s immunity through past infections and vaccinations.
