The CD56 (NK Cells) blood test evaluates the number of natural killer cells, a type of white blood cell that helps protect your body from viruses, infections, and abnormal cell growth. These cells are a key part of your immune system’s first line of defence. Abnormal NK cell levels may indicate immune system dysfunction or help monitor immune-related or inflammatory conditions.
