What is the immune system?
The immune system is a complex network of cells known as immune cells that include lymphocytes.

What are the two types of lymphocytes?
Share on Pinterest. Lymphocytes are white blood cells that are part of the immune system. There are two categories of lymphocytes known as B lymphocytes and T lymphocytes. These are commonly referred to as B cells and T cells. Both types originate from stem cells in the bone marrow.
What is the job of B cells?
The job of B cells is to make antibodies, which are proteins produced by the immune system to fight foreign substances known as antigens. Each B cell is set to make one specific antibody.

B cells are formed in bone marrow, the spongy tissue inside certain bones. They provide humoral immunity, which is immunity against pathogens circulating in blood (outside of cells).
How to collect blood sample?
The required amount of blood sample is collected by pulling the plunger of the syringe out slowly
Where are B cells formed?
B cells are formed in bone marrow, the spongy tissue inside certain bones. They provide humoral immunity, which is immunity against pathogens circulating in blood (outside of cells).

Optimal Result: 20 - 40 %. Lymphocytes are cells that work in our immune system and thus belong to the white blood cell family.
