5 Lab Tests Every Healthy Person Misses: Detecting and Managing Silent Inflammation
5 Lab Tests Every Healthy Person Misses: Detecting and Managing Silent Inflammation
By Chris Duffin
You can appear healthy on the outside, train consistently, and follow a disciplined lifestyle, yet still experience internal inflammation that quietly accelerates aging and reduces performance. Silent inflammation is a subclinical process that disrupts cellular signaling, hormone balance, and recovery long before symptoms appear. Chronic exposure to oxidative stress, environmental toxins, or overtraining can sustain this inflammatory state, creating the conditions for fatigue, joint pain, cognitive decline, and poor body composition.The solution is data.
The following five biomarkers provide an early and measurable window into your body’s inflammatory status. When tracked consistently and interpreted properly, they allow for targeted intervention to restore cellular health, optimize recovery, and enhance longevity.
1. hs-CRP (High-Sensitivity C-Reactive Protein)
What it measures:
hs-CRP is a highly sensitive marker of systemic inflammation produced by the liver in response to cytokines such as interleukin-6 (IL-6). It reflects the total inflammatory burden in the body, including endothelial stress, tissue repair processes, and immune activation.
Why it matters:
Elevated hs-CRP correlates with increased risk of cardiovascular disease, metabolic dysfunction, and impaired recovery. Even mild elevations can signify chronic low-grade inflammation that undermines cellular performance.
Optimal range: < 1.0 mg/L
What to do:
Persistent elevation should prompt an evaluation of training volume, sleep quality, and micronutrient status. Functional interventions include mitochondrial support peptides (MOTS-c), Fatty15 or omega-3 supplementation, and targeted antioxidant therapy.
2. Interleukin-6 (IL-6)
What it measures:
IL-6 is a cytokine secreted by immune cells, muscle tissue, and adipocytes. It serves as both a pro- and anti-inflammatory signal, depending on duration and context. Transient IL-6 elevations during exercise promote adaptation, while chronic elevation indicates sustained immune activation.
Why it matters:
Chronically high IL-6 levels impair insulin sensitivity, suppress anabolic signaling, and contribute to fatigue and delayed recovery. Elevated IL-6 also drives hepatic production of CRP, amplifying systemic inflammation.
Optimal range: < 2 pg/mL
What to do:
Reducing chronic IL-6 requires improved sleep architecture, blood sugar regulation, and stress management. Adjunctive interventions such as Thymosin Alpha-1 or BPC-157 can help modulate immune balance and reduce persistent inflammatory signaling.
3. Ferritin
What it measures:
Ferritin is an intracellular protein that stores and releases iron. It also functions as an acute-phase reactant, increasing in response to inflammation and oxidative stress.
Why it matters:
High ferritin levels in the absence of iron overload often indicate metabolic inflammation and oxidative damage. Elevated ferritin can impair mitochondrial function, disrupt hormone conversion, and increase cardiovascular risk.
Optimal range: 50–150 ng/mL (context dependent)
What to do:
Address possible contributors such as poor sleep, excess alcohol intake, or chronic stress. Support detoxification pathways through proper hydration, antioxidant-rich nutrition, and mitochondrial restoration protocols (MOTS-c, CoQ10, or glutathione precursors).
4. Gamma-Glutamyl Transferase (GGT)
What it measures:
GGT is a hepatic enzyme involved in glutathione metabolism. It reflects oxidative stress, toxin exposure, and hepatic burden rather than isolated liver pathology.
Why it matters:
Even modest elevations in GGT are associated with increased oxidative stress, impaired detoxification capacity, and reduced longevity. High GGT levels often coincide with metabolic inflammation and mitochondrial dysfunction.
Optimal range: < 20 U/L
What to do:
Evaluate environmental toxin exposure, medication burden, and alcohol consumption. Interventions include glutathione support, redox-balancing nutrients, and mitochondrial optimization peptides such as SS-31 or MOTS-c.
5. Homocysteine
What it measures:
Homocysteine is a sulfur-containing amino acid formed during methionine metabolism. Elevated levels indicate impaired methylation and endothelial dysfunction.
Why it matters:
High homocysteine increases oxidative stress, promotes vascular damage, and contributes to neurodegenerative risk. It also interferes with nitric oxide signaling, limiting blood flow and nutrient delivery during exercise.
Optimal range: 6–8 µmol/L
What to do:
Support methylation with adequate folate (5-MTHF), vitamin B12 (methylcobalamin), and vitamin B6. Evaluate thyroid function, gut health, and oxidative stress levels to address upstream contributors.
Bringing It All Together
Inflammation is not a single disease process but a systemic dysfunction that undermines nearly every aspect of human performance. The ability to detect and correct early inflammatory shifts determines how well you recover, think, and age.
Tracking hs-CRP, IL-6, Ferritin, GGT, and Homocysteine creates a performance baseline. From there, we can implement targeted interventions — from peptide therapies such as Thymosin Alpha-1 and BPC-157, to nutrition, recovery, and environmental optimization — to bring your system back into equilibrium.
