Serum Adiponectin (Adiponectin)
Adiponectin is an abundant insulin-sensitizing and anti-inflammatory protein secreted by adipocytes that stimulates cellular fatty acid oxidation and glucose uptake via AMPK activation.
Standard vs. Optimal Reference Rangesμg/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.
4.0 - 26.0 μg/mL
General reference distribution across unselected commercial populations.
> 12.0 μg/mL (Male), > 15.0 μg/mL (Female)
Concentration target associated with minimal all-cause cardiometabolic mortality.
Molecular Mechanism & Clinical Purpose
Binds AdipoR1 and AdipoR2 receptors, activating 5'-AMP-activated protein kinase (AMPK) and peroxisome proliferator-activated receptor alpha (PPAR-alpha) to enhance mitochondrial beta-oxidation and suppress hepatic gluconeogenesis.
Differential Diagnosis
Elevated Levels (Adiponectin High)
- •High insulin sensitivity and metabolic longevity phenotype
- •Caloric restriction
- •Advanced heart failure (paradoxical elevation / wasting)
Low Levels (Adiponectin Low)
- •Visceral adiposity and hypertrophic adipocytes
- •Type 2 Diabetes Mellitus
- •Coronary artery disease

Pre-Analytical Caveats & Diagnostic Workup
Pre-Analytical Considerations:
Strict 10 to 12 hour overnight water-only fasting is mandatory for baseline metabolic quantification. Acute psychological stress, acute infectious illness, and sleep deprivation (<6 hours) transiently elevate cortisol and catecholamines, falsely elevating glycemic markers. For glucose and insulin testing, draw blood into sodium fluoride/potassium oxalate tubes or separate serum promptly within 30 minutes to prevent ongoing in vitro red blood cell glycolysis.
Reflexive Testing Protocol:
- Homeostatic Model Assessment of Insulin Resistance (HOMA-IR) and HOMA-Beta calculations
- Continuous Glucose Monitoring (CGM) 14-day wear to evaluate glycemic variability and postprandial excursions
- Fasting C-Peptide and high-sensitivity Troponin/hs-CRP to differentiate insulin resistance from beta-cell exhaustion
- Oral Glucose Tolerance Test (OGTT) with simultaneous 0, 30, 60, and 120-minute insulin assays
- Abdominal ultrasound or FibroScan to evaluate hepatic steatosis and non-alcoholic fatty liver disease (MASLD)
