[Allergens used in skin tests in Mexico]

Area of Science:

• Clinical Immunology
• Allergology
• Diagnostic Testing

Context:

• Immunotherapy is the primary causal treatment for allergies, requiring precise allergen identification.
• Skin prick testing (SPT) is essential for allergy diagnosis, relying on an adequate allergen panel.
• Allergen selection for SPT is critical for accurate diagnosis and treatment planning.

Purpose:

• To determine the specific allergens utilized in allergy practices across Mexico.
• To survey the composition of routine skin prick tests (SPT) employed by allergists in Mexico.

Summary:

• A national survey of Mexican allergy specialists revealed that while common allergens like Atriplex are widely used, some important allergens (cat, dog, cockroach) are omitted in a significant percentage of practices.
• Results indicate variability in SPT allergen composition, with some practices not testing for key environmental allergens.
• Weeds are adequately represented, but omissions in tree allergens and common indoor allergens like pet dander and cockroach are noted.

Impact:

• Highlights potential gaps in current diagnostic practices for allergies in Mexico.
• Emphasizes the need for continuous re-evaluation and standardization of SPT allergen panels based on evolving research.
• Underscores the role of allergists in adapting diagnostic tools for optimal patient care and effective immunotherapy.
