Available laboratory indicators of the severity of inflammation include C-reactive protein (CRP), procalcitonin (PCT), interleukin 6 (IL-6), serum amyloid A (SAA), ferritin (FER), neutrophil CD64, and heparin-binding protein (HBP), among others, whose values are indicative of the type or severity of infection. Here, AZU1 is linked to infection.
