What could be the cause for low nuetrophils and high lymphocytes?

Question

neutrophils 20 and lymphocytes 60

Answer 1

With the limited information I will take a stab at the answer. The most common cause of low neutrophils and high lymphocytes is a viral infection. The most simple way to explain is the lymphocytes are responsible for antibody production and are increased during viral attack. Neutrophils are responsible for phagocytosis (ingestion) of bacteria during a bacterial caused disease. There can be other reasons but this is the most common, therefore the most likely.
