How are STI Test and allergy related?

The relationship between STI testing and allergies is not directly supported by evidence. STI tests detect pathogens or antibodies against infections, while allergy tests measure IgE responses to harmless allergens. An indirect link may exist via immune system modulation: chronic infections or microbiome disruption (e.g., from antibiotics) could influence allergy risk. However, no validated biomarkers combine both areas. The provided knowledge context contains no studies or products linking STI and allergy. Therefore, the evidence is unclear. Consumers should not rely on combined tests and should seek separate medical advice for STI and allergy concerns.
