PROVIDER INITIATED TEST - The Natural Killer (NK) Cells test measures the number and proportion of NK cells in the blood. NK cells are a type of white blood cell that play a critical role in innate immune defense, helping the body recognize and destroy virus-infected cells and abnormal or cancerous cells.
This test is commonly used to evaluate immune system function and may be ordered when investigating recurrent infections, chronic viral illness, immune deficiencies, autoimmune conditions, or overall immune health. NK cell testing is often performed as part of a lymphocyte subset or immune function panel.
