Serum Interleukin-1 Beta (IL-1beta)
Potent pyrogenic cytokine produced following cleavage of pro-IL-1beta by caspase-1 within activated NLRP3 inflammasomes.
Standard vs. Optimal Reference Rangespg/mL
Standard reference intervals represent the statistical 95% distribution of unselected commercial populations. Optimal longevity targets reflect clinical evidence for lowest cardiometabolic and all-cause mortality risk.
Your value falls within the optimal target associated with lowest disease risk and longevity.
<5.0 pg/mL
General reference distribution across unselected commercial populations.
<1.0 pg/mL (undetectable)
Concentration target associated with minimal all-cause cardiometabolic mortality.
Molecular Mechanism & Clinical Purpose
Binds IL-1R1, recruiting MyD88 to activate NF-kB and drive secondary transcription of IL-6 and adhesion molecules.
Differential Diagnosis
Elevated Levels (IL-1beta High)
- •NLRP3 inflammasome activation (gout, pseudogout)
- •Atherosclerosis and ACS
- •Autoinflammatory syndromes
Low Levels (IL-1beta Low)
- •Quiescent inflammasome state
- •Targeted IL-1beta inhibition (Canakinumab)

Pre-Analytical Caveats & Diagnostic Workup
Pre-Analytical Considerations:
Collect in standard collection tubes as specified by the laboratory protocol. Avoid hemolysis and process serum/plasma promptly within 2 hours. Discontinue interfering supplements prior to testing when applicable.
Reflexive Testing Protocol:
- Confirmatory testing and secondary biomarker panel evaluation for IL-1beta
- Targeted imaging or functional organ assessment related to nlrp3 inflammasome activation
- Comprehensive metabolic and inflammatory baseline panel (CMP, CBC, hs-CRP)
