Inflammation Markers
Understanding inflammatory biomarkers—what chronic inflammation looks like in labs and how to address it.
📖 The Story
Click to expand
David's labs always came back "normal." Cholesterol fine, blood sugar fine, kidney and liver fine. But he felt increasingly unwell—joint pain, brain fog, stubborn belly fat, and a general sense of inflammation.
His new doctor ran tests his previous doctors hadn't: hs-CRP, homocysteine, and ferritin.
The results revealed what standard panels missed. His hs-CRP was 4.2 mg/L—technically below the "high" threshold but indicating significant chronic inflammation. His homocysteine was 14 μmol/L—associated with cardiovascular risk and B vitamin status. His ferritin was 325 ng/mL—in range but elevated in a way that suggested inflammation, not just iron stores.
"You have systemic inflammation," his doctor explained. "It's not causing obvious disease yet, but it's driving your symptoms and increasing your risk for everything from heart disease to dementia."
With targeted interventions—anti-inflammatory diet, omega-3s, B vitamins, stress reduction—David's markers normalized over six months. His symptoms resolved. He didn't just feel better—he'd addressed a root cause that standard testing had missed.
The lesson: Chronic inflammation underlies most modern diseases. Testing inflammatory markers reveals what standard panels don't—and offers a chance for intervention before disease develops.
🚶 The Journey
Understanding Inflammation
Acute vs. Chronic Inflammation:
| Acute Inflammation | Chronic Inflammation |
|---|---|
| Response to injury/infection | Persistent, low-grade |
| Protective and necessary | Damaging and disease-driving |
| Visible symptoms (swelling, redness) | Often "silent" |
| Resolves naturally | Persists without intervention |
| Hours to days | Months to years |
Chronic inflammation is called the "silent killer" because it drives disease without obvious symptoms.
🧠 The Science
Understanding Inflammatory Markers
Key Inflammatory Markers
High-Sensitivity C-Reactive Protein (hs-CRP):
| Level | Interpretation |
|---|---|
| <1.0 mg/L | Low inflammation (optimal) |
| 1.0-3.0 mg/L | Moderate inflammation |
| >3.0 mg/L | High inflammation |
| >10 mg/L | Likely acute infection/condition |
What hs-CRP Indicates:
- Produced by liver in response to inflammation
- Non-specific (doesn't tell you WHERE)
- Cardiovascular risk predictor
- General inflammation indicator
- Can spike with acute infection (use average)
Erythrocyte Sedimentation Rate (ESR):
| Level | Interpretation |
|---|---|
| Men: 0-15 mm/hr | Normal |
| Women: 0-20 mm/hr | Normal |
| Elevated | Inflammation present |
What ESR Indicates:
- How quickly red cells settle (inflammation makes them clump)
- Non-specific marker
- Often elevated in autoimmune conditions
- Slower to change than CRP
Homocysteine:
| Level | Interpretation |
|---|---|
| <7 μmol/L | Optimal |
| 7-10 μmol/L | Acceptable |
| 10-15 μmol/L | Elevated (CVD risk) |
| >15 μmol/L | High (significant risk) |
What Homocysteine Indicates:
- Amino acid metabolite
- Elevated with B vitamin deficiency (B12, folate, B6)
- Associated with cardiovascular disease
- May indicate methylation issues
- Responds well to B vitamin supplementation
Ferritin:
| Level | Interpretation |
|---|---|
| 15-150 ng/mL (women) | Lab normal |
| 30-300 ng/mL (men) | Lab normal |
| 50-150 ng/mL | Often optimal |
| Elevated without iron excess | May indicate inflammation |
Ferritin as Inflammatory Marker:
- Primary iron storage marker
- BUT also acute phase reactant
- Elevated in inflammation (even with low iron)
- Very high (>500) often inflammatory
- Context matters (check iron panel)
Other Markers:
| Marker | What It Indicates | Optimal |
|---|---|---|
| Fibrinogen | Clotting + inflammation | 200-350 mg/dL |
| Uric acid | Metabolism + inflammation | <6 mg/dL |
| GGT | Liver + oxidative stress | <30 U/L |
| LDH | Tissue damage | Normal range |
| WBC | Immune activity | 4-10 K/μL |
What Drives Chronic Inflammation
Common Causes:
| Category | Examples |
|---|---|
| Diet | Processed foods, sugar, seed oils, food sensitivities |
| Gut | Leaky gut, dysbiosis, infections |
| Metabolic | Obesity, insulin resistance, metabolic syndrome |
| Lifestyle | Sleep deprivation, chronic stress, sedentary |
| Environmental | Toxins, pollutants, mold |
| Infections | Chronic low-grade infections (dental, gut) |
| Autoimmune | Immune system attacking self |

- Exercise: regular, moderate
- Omega-3s, vitamin D if deficient
- Retest after 3 months
-
"My homocysteine is 14":
- Elevated (optimal <8)
- Often indicates B vitamin deficiency
- B12, folate, B6 typically help
- Retest after 2-3 months supplementation
- Associated with cardiovascular risk
## ❓ Common Questions
Q: What's the difference between CRP and hs-CRP? A: hs-CRP (high-sensitivity) can detect lower levels of inflammation. Regular CRP is for detecting significant inflammation (infections, autoimmune flares). For cardiovascular risk and chronic low-grade inflammation, hs-CRP is needed.
Q: Can inflammation cause weight gain? A: Yes. Inflammation promotes insulin resistance, which drives fat storage. And fat tissue produces inflammatory cytokines, creating a vicious cycle. Reducing inflammation can help weight loss, and weight loss reduces inflammation.
Q: How long does it take to reduce inflammation? A: Dietary changes can reduce hs-CRP within 2-4 weeks. Significant changes typically take 2-3 months. Some inflammation sources (gut, chronic infections) may take longer to address. Test and track progress.
Q: Is all inflammation bad? A: No—acute inflammation is necessary and protective (injury response, fighting infection). The problem is chronic, low-grade inflammation that persists without resolution. That's what drives disease.
Q: Can stress alone cause elevated inflammatory markers? A: Yes. Chronic stress elevates cortisol, which can dysregulate immune function and increase inflammation. Stress management is a legitimate anti-inflammatory intervention.
