was bedeutet crp beim blutbild — can a DNA test help?

CRP (C-reactive protein) is a blood marker for inflammation. Elevated levels can indicate acute or chronic inflammation, infection, tissue damage, or lifestyle factors. A DNA test can theoretically identify genetic variants in genes like CRP or IL6 that are associated with slightly higher baseline CRP levels. However, the effect sizes are very small (often <0.1 mg/L) and clinically irrelevant. A DNA test cannot replace a blood test. The cause of an elevated CRP must be evaluated by a doctor. Direct-to-consumer DNA tests for CRP are of limited value and should not be used for self-diagnosis or treatment decisions.
