Evidence check: CRP Entzündung in the context of allergy

CRP (C-reactive protein) is a non-specific inflammatory marker that rises in many acute and chronic inflammatory conditions, including allergies. Studies show that CRP can be moderately elevated in allergic rhinitis or asthma, especially during exacerbations or severe disease. However, CRP is not specific to allergy; it also increases in infections, tissue damage, or stress. A normal CRP does not rule out allergic inflammation, which is often local (e.g., in airways) without strong systemic effects. For allergy diagnosis, specific IgE and provocation tests are more reliable. The evidence for CRP in allergy is moderate: it may serve as a supplementary marker in severe asthma but not for screening. The provided context does not directly link CRP to allergies. Caution: elevated CRP must be interpreted in the full clinical picture.
