​Introduction: Cytokine Storm—A Double-Edged Sword of the Immune System
When the body encounters viruses (such as SARS-CoV-2) or severe infections, the immune system may become overactivated, triggering a ​cytokine storm. During this process, pro-inflammatory factors like ​interleukin-6 (IL-6) surge rapidly in bodily fluids, leading to systemic inflammatory responses and multiple organ failure, posing a critical challenge in clinical treatment. Precise monitoring of IL-6 levels is not only essential for early warning of cytokine storms but also pivotal for optimizing therapeutic decisions and saving lives.

​IL-6: The "Core Early-Warning Biomarker" of Cytokine Storms
As a pleiotropic cytokine, IL-6 plays a dual role in immune regulation, inflammatory responses, and tissue damage:

​Physiological Role: Released by macrophages, endothelial cells, and others, it activates innate and adaptive immunity to clear pathogens and damaged tissues.
​Pathological Mechanism: When IL-6 is overproduced, it exacerbates conditions through:
​Vascular Leakage: Disrupts the endothelial barrier, causing pulmonary edema and acute respiratory distress syndrome (ARDS).
​Coagulation Dysregulation: Activates the coagulation cascade, increasing thrombosis risk.
​Multi-Organ Damage: Drives abnormal elevation of acute-phase proteins (e.g., CRP, SAA) in the liver, amplifying systemic inflammation.
The Expert Consensus on Clinical Significance of Infection-Related Biomarkers clearly states: ​IL-6 is the most sensitive inflammatory biomarker. Its dynamic changes provide earlier warnings of disease progression than traditional markers (e.g., CRP, PCT), offering irreplaceable predictive value in sepsis, severe COVID-19, and CAR-T therapy complications.

​New Trends in Precision Diagnostics: IL-6 Combined Testing and POCT Market Opportunities
With advancements in precision medicine, the limitations of single biomarkers are becoming evident. Clinical evidence highlights:

​IL-6 + PCT Combined Testing (IP Panel): Balances sensitivity and specificity for rapid differentiation of infection types (bacterial vs. viral) and treatment monitoring.
​POCT Technological Innovation: Point-of-care testing (POCT), with its speed and portability, is in surging demand in emergency and ICU settings. China’s POCT market is projected to grow at over 20% annually, with ​inflammatory infection biomarkers occupying the largest share. As a core indicator, IL-6 holds immense market potential.
