IL6 and Sepsis: The most clinically relevant biomarkers are C‐reactive protein (CRP), interleukin‐6 (IL‐6), and procalcitonin (PCT), whose serum concentrations increase in sepsis.[47, 48] CRP is known for its high sensitivity, but low specificity for sepsis identification, as its levels are also influenced by chronic conditions such as autoimmune diseases or by other triggers (e.g., trauma).[49, 50, 51, 52] By measuring the kinetics of the CRP level, conclusions can be drawn about the course of the disease.
