What role does HbA1c play in Allergie?

HbA1c (glycated hemoglobin) is a well-established long-term blood glucose marker, primarily used for diagnosing and monitoring diabetes mellitus. In allergology, HbA1c plays no direct, standard role. However, some epidemiological studies suggest that elevated HbA1c levels may be associated with increased systemic inflammation, potentially linked to allergic conditions such as asthma or atopic dermatitis. The mechanism remains unclear; hypotheses include immune dysregulation due to hyperglycemia or shared metabolic dysfunction. The evidence is weak and insufficient to recommend HbA1c as a biomarker for allergies. In practice, HbA1c is measured in allergy patients only if concurrent diabetes or metabolic syndrome is suspected. In summary: HbA1c is not an allergy marker; any connection is indirect and requires further research. At MyBody-X, HbA1c is included in metabolic analysis, not allergy diagnostics.
