The adaptive (specific) immune system makes antibodies and uses them to specifically fight certain germs that the body has previously come into contact with.

Normal ranges and levels The normal lymphocyte range in adults is between 1,000 and 4,800 lymphocytes in 1 microliter (µL) of blood. In children, the normal range is between 3,000 and 9,500 lymphocytes in 1 µL of blood. Unusually high or low lymphocyte counts can be a sign of disease.

What are the two types of innate immunity?

What are the difference between innate and acquired immunity?
