Allergy Testing in Horses

At present, a definitive diagnosis of IBH and atopy is based on the history (seasonality, recurrence and response to insect control), physical examination, and exclusion of other pruritic skin diseases such as those involving ectoparasites, bacterial, yeast or fungal infections, and food and contact allergies.

PAX Serum Test

When the presence of IBH or atopy has been established, PAX Serum Test can be performed to identify the responsible allergens. PAX is an innovative horse-specific test with high specificity and sensitivity.

PAX® is the first commercial serological IgE-specific test that uses allergen extracts and molecular components to identify allergen sensitivities.

Molecular allergology is a state-of-the-art approach to the detection of sensitisations, whereby defined single allergen components are used for the determination of specific IgE in place of traditionally-used allergen extracts. The molecular components are purified or recombinant proteins that provide a higher level of standardisation than allergen extracts and enable a more precise identification of IgE sensitisations.

This is a fundamental step to develop a relevant immunotherapy treatment or implement allergen-avoidance measures.

Allergy treatment

Intradermal Skin Test

In addition to PAX, an intradermal skin test can also be performed. Small amounts of different allergens are injected subcutaneously, allowing evaluation of any local reaction that develops at the site of the injection.
