How are hsCRP and Allergie related?

The relationship between hsCRP (high-sensitivity C-reactive protein) and allergies is indirect and non-specific. hsCRP is a systemic inflammatory marker that rises in many inflammatory conditions, including allergic reactions. Allergies such as hay fever, asthma, or atopic dermatitis involve local and sometimes systemic inflammation, which can elevate hsCRP levels. However, hsCRP is not a specific marker for allergies—it also responds to infections, tissue damage, metabolic inflammation, or autoimmune diseases. The evidence is mixed: some studies show moderate correlations between hsCRP and allergic diseases, while others find no significant association. Additionally, factors like obesity, smoking, or genetic variants (e.g., in IL-6 or CRP genes) can influence levels. From a personalized diagnostics perspective, hsCRP alone is insufficient to confirm or rule out an allergy. It may serve as a supplementary indicator of ongoing inflammation but should always be interpreted alongside specific allergy tests (IgE, skin tests). The provided context does not contain direct evidence linking hsCRP and allergies, so the strength of any conclusion remains limited.
