NK cells or Natural Killer Cells are white blood cells that help guard the body viruses and tumor cells. Therefore, the function of your NK cells determines how good your immune function is Poor NK cell activity reflects impaired immune function.

Common cause of poor NK cell activity are:

Cancer
Family history of cancer
Imbalanced lifestyle e.g Heavy cigarette smoking, sleep deprivation, high stress, obesity
Poor nutrition e.g insufficient intake of fruit and vegetables, low protein intake etc.
Specific medications e.g immunosuppressive agents, chemotherapy drugs
Post-surgery

High NK cell activity reflects a good immune system. However, if the level is abnormally high, one must suspect the presence of infection or autoimmune diseases such as SLE or Rheumatoid arthritis.
