Serum Interleukin-10 (IL-10)
Master anti-inflammatory cytokine produced by regulatory T cells and M2 macrophages that limits pro-inflammatory damage.
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.
1.0 - 10.0 pg/mL
General reference distribution across unselected commercial populations.
3.0 - 8.0 pg/mL
Concentration target associated with minimal all-cause cardiometabolic mortality.
Molecular Mechanism & Clinical Purpose
Binds IL-10R1/IL-10R2 complex, activating STAT3 to downregulate macrophage MHC-II and suppress IL-1, IL-6, TNF-alpha.
Differential Diagnosis
Elevated Levels (IL-10 High)
- •Systemic compensatory anti-inflammatory response
- •Certain B-cell lymphomas
- •Normal Treg activation
Low Levels (IL-10 Low)
- •Severe autoimmune disease with impaired tolerance
- •Defective immune checkpoint suppression

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-10
- Targeted imaging or functional organ assessment related to anti-inflammatory cytokine tolerance
- Comprehensive metabolic and inflammatory baseline panel (CMP, CBC, hs-CRP)
