Diagnosis
The veterinarian will ask the owner about the animal's history of symptoms. During the physical examination, the presence of itching and skin lesions will be assessed. Before concluding a diagnosis of inhalant allergy, the veterinarian will need to rule out other skin diseases including food hypersensitivity, flea allergy dermatitis, sarcoptic mange, contact dermatitis, and yeast infection of the skin. Diagnostic procedures can include bloodwork and urinalysis, and skin scrapings, and fungal cultures. Intradermal skin testing is believed to be the most accurate of the allergy tests; this procedure should be performed by an experienced veterinarian or by a veterinary dermatologist. There are also blood tests which, while they are unreliable for felines, may provide information about inhalant allergies for canines.
