CRP (C-reactive protein) is a liver-produced inflammation marker. It rises during acute infections, chronic inflammation, or tissue damage. For preventive screening, high-sensitivity CRP (hs-CRP) is used to estimate cardiovascular risk: levels below 1 mg/L indicate low risk, above 3 mg/L elevated risk. However, CRP is non-specific – colds, smoking, or obesity also raise it. Other important blood markers include the lipid panel (LDL, HDL, triglycerides), fasting glucose and HbA1c for glucose metabolism, plus liver and kidney function tests. MyBody-X offers some of these via home tests, but clinical validation for the specific test combination is often lacking. Evidence for CRP as a standalone predictor is moderate; medical interpretation is essential. Elevated values require diagnostic workup before starting supplements or diets.
