Systemic Inflammation Quantification is the clinical process of objectively measuring the level of chronic, low-grade, generalized inflammatory activity present throughout the body, often without overt symptoms of acute infection. This is achieved by assessing circulating biomarkers, such as high-sensitivity C-Reactive Protein (hs-CRP), interleukin-6 (IL-6), and fibrinogen. Quantifying this subclinical inflammation is crucial because it is a foundational driver of numerous age-related diseases and hormonal dysregulation.
Origin
This term is a clinical and analytical construct, combining ‘systemic inflammation,’ referring to a body-wide, non-localized immune response, with ‘quantification,’ meaning the process of measurement. Its origin is in advanced clinical pathology and cardiovascular risk assessment, where low-grade inflammation was identified as a critical, modifiable risk factor. The emphasis on quantification reflects the necessity of precise, measurable data for effective therapeutic intervention.
Mechanism
The measurement mechanism relies on laboratory assays that detect the concentration of specific pro-inflammatory and acute-phase proteins released into the bloodstream, primarily by the liver and immune cells. These proteins are synthesized in response to chronic stressors, adipose tissue dysfunction, or gut dysbiosis, which trigger the activation of transcription factors like NF-κB. The resulting biomarker levels provide a numerical proxy for the overall inflammatory burden impacting all body systems.
