The immune system is the body’s natural defense mechanism, composed of tissues, cells, organs, and biological molecules. Its primary function is to prevent and combat diseases. A strong immune system reduces the risk of infections and various illnesses.
Types of Immunity
Importance of the Immune System
A well-functioning immune system acts like a strong defense force, protecting the body from bacteria, viruses, and other harmful invaders. Small pathogens like viruses can be effectively attacked, whereas larger threats like tumors require a stronger immune response. A robust immune system helps prevent infections, cancer, and other diseases, ensuring overall well-being.
Function of NK Cells
NK cells are a crucial component of the innate immune system, acting as the body’s first responders to foreign threats. The body typically contains 2–5 billion NK cells, which can identify and eliminate harmful cells within 24 hours. Their key functions include:
Measuring NK Cell Count
NK Cell Count can help determine the levels of NK cells in the bloodstream. People who have low levels of NK cells, might get a higher risk of developing cancer or infectious diseases.
These measurements help doctors evaluate immune amount and strength, as various factors like stress, poor sleep, or inadequate nutrition can lower NK cell amount and activity, increasing susceptibility to illnesses. Although they do not diagnose specific diseases, they aid in determining the need for further medical screening.
Who Should Get NK Cell Count and NK Cell Activity Tests?
Boosting Immunity with NK Cell Therapy
If NK cell count and activity are below normal levels , they may indicate early-stage health concerns. Even individuals with normal NK count and activity should maintain immune health. Doctors may recommend personalized immune-boosting strategies, including:
