Evidence check: CRP Entzündung in the context of Haut

CRP (C-reactive protein) is a well-established but non-specific marker of inflammation. Elevated levels can indicate systemic inflammation that may affect the skin—for example in psoriasis, acne, or chronic wounds. However, a single CRP value does not reveal the cause or location of inflammation. Skin-specific inflammatory processes are often better assessed by local cytokines or clinical examination. Consumer lab tests measuring CRP provide a rough indication but not a diagnosis. Evidence for CRP as a standalone skin marker is moderate; studies show associations but not causality. Caveat: Elevated CRP requires medical follow-up, especially with concurrent skin symptoms. False positives can cause unnecessary worry. Interpretation must always consider clinical context. MyBody-X tests include CRP as part of a broader inflammation panel, but its limitations should be recognized.
