What does the High-Sensitivity C-Reactive Protein test measure?

Q: Why is High-Sensitivity C-Reactive Protein measured?

Elevated hs-CRP has been observed in some cohorts of children and adults with ADHD, though findings are inconsistent and causality is not established. It is included in comprehensive functional panels as a general marker of systemic inflammation, not as a diagnostic or specific marker of ADHD.

High-Sensitivity C-Reactive Protein (hs-CRP) is a clinical biomarker used in comprehensive-panels assessment. C-reactive protein is an acute-phase reactant synthesised by the liver in response to IL-6 and other inflammatory cytokines. It is measured in 1 laboratory test on BiomarkersLabs.com.

What is High-Sensitivity C-Reactive Protein?

C-reactive protein is an acute-phase reactant synthesised by the liver in response to IL-6 and other inflammatory cytokines. High-sensitivity assays detect low-grade chronic inflammation associated with metabolic and cardiovascular disease. Neuroinflammation and peripheral inflammatory markers have been investigated as potential contributors to psychiatric and neurodevelopmental disorders.
