Clinical Significance
Like respiratory allergies, animal allergies pose a significant risk for the development of asthma and rhinitis. Blood IgE tests using whole allergen extracts from horses provide a sensitive screening method to diagnose pet sensitization. In addition, the horse dander component panel is an IgE blood test using individual recombinant proteins from horses, improving specificity compared to animal extract assays. Thus, the horse dander component panel helps differentiate an actual horse allergy from a cross-reactive pet allergy.
