Understanding High-Sensitivity C-Reactive Protein (hs-CRP): Normal vs Optimal Ranges
Also known as: c-reactive protein cardio, hscrp, high sensitivity crp, cardio crp
?What is High-Sensitivity C-Reactive Protein (hs-CRP)?
High-sensitivity C-reactive protein (hs-CRP) is an inflammatory marker produced by the liver in response to systemic inflammation. It is more sensitive than standard CRP and is specifically used to assess cardiovascular risk. Elevated levels may suggest chronic inflammation that could be associated with atherosclerosis and cardiovascular disease.
!Why It Matters
hs-CRP can help identify individuals at increased risk for heart attack and stroke, independent of cholesterol levels. It may suggest chronic low-grade inflammation, which can be associated with atherosclerosis progression and thrombotic events. Monitoring hs-CRP alongside traditional cardiovascular risk factors provides a more complete picture of cardiac health.
Reference Ranges
| Range Type | Min | Max | Unit | Note |
|---|---|---|---|---|
| Lab Normal | 0 | 3 | mg/L | Standard lab reference range |
| Optimal | 0 | 1 | mg/L | Evidence-based optimal range for health |
| Longevity Target | 0 | 1 | mg/L | Per longevity medicine research (Attia et al.) |
Lab normal ranges may vary between laboratories. Optimal and longevity targets are based on research literature and should be interpreted with your physician.
Symptoms of Imbalance
- Chest discomfort or angina
- Shortness of breath
- Fatigue
- Recurrent infections or illness
- Joint or muscle pain
How to Improve Your Levels
- 1Engage in regular aerobic exercise (150 minutes per week)
- 2Adopt a heart-healthy diet rich in omega-3 fatty acids, whole grains, and antioxidants
- 3Reduce refined sugar and processed food intake
- 4Maintain a healthy body weight
- 5Manage stress through meditation, yoga, or counseling
- 6Avoid smoking and limit alcohol consumption
When to Test
hs-CRP is typically tested as part of cardiovascular risk stratification, especially in individuals with family history of heart disease, metabolic syndrome, or those over age 50. It may also be useful in those with chronic inflammatory conditions or after lifestyle interventions to monitor progress.
