Interleukin-8, Plasma

This test measures the level of Interleukin-8 (IL-8), a protein in your blood that signals immune cells to move toward areas of infection or injury. It helps doctors evaluate the intensity of inflammation in the body, which is useful for monitoring severe infections or chronic immune conditions. While this measurement provides insight into immune system activity, it cannot pinpoint the specific location or underlying cause of the inflammation by itself.
