CRP (C-reactive protein) is a blood marker for inflammation. The high-sensitivity CRP test (hsCRP) is used in clinical practice to assess cardiovascular risk: levels <1 mg/L indicate low risk, 1–3 mg/L moderate, and >3 mg/L high risk. However, CRP is non-specific – infections, injuries, or chronic inflammation can also raise levels. A single elevated value is not diagnostic; it should be interpreted alongside a full lipid panel and possibly repeated. Can a DNA test help? The provided context contains no evidence that a DNA test like MyBody-X can directly predict or influence CRP levels. While genetic variants (e.g., in the CRP gene) exist that modestly modulate baseline CRP, these are typically not included in consumer DNA tests or have very small effect sizes. The evidence for using DNA tests to assess CRP is weak and unsupported by the available sources. For reliable CRP measurement, a blood test remains the gold standard.
