Lymphocytes in a blood test are a type of white blood cell that play a crucial role in your immune system, helping your body fight infections.
Understanding Lymphocytes
Lymphocytes are essential components of the immune system. Here's a closer look at their function and significance:
- Immune System Role: Lymphocytes are responsible for identifying and destroying foreign invaders like bacteria, viruses, and other pathogens.
- Types of Lymphocytes: There are three main types:
- B cells: Produce antibodies to neutralize pathogens.
- T cells: Directly kill infected cells and regulate the immune response.
- Natural killer (NK) cells: Attack and destroy abnormal cells, such as cancer cells.
What Does a High Lymphocyte Count Mean?
According to the provided reference, a temporarily high lymphocyte count usually indicates that your body is actively fighting off an infection or responding to a vaccination. This is a sign that your immune system is working effectively to protect you from illness.
