Intradermal Allergy Testing

Intradermal Allergy Testing

We consult with Dr. Alexander Werner, a boarded veterinary dermatologist from Animal Dermatology Center in Los Angeles in challenging skin and allergy cases.  An alternative allergy testing that is thought to be more sensitive but run in conjunction with serum testing is intradermal testing.


An area is clipped on the neck of the horse.  Using a permanent marker, injection sites are pre-marked on the skin.

A specific allergen is then injected into each site.

The sites are monitored for changes in size indicating a reaction to that specific allergen.


After the site reactions have been recorded, the veterinarian can make specific recommendations for allergy treatments or food avoidances in conjunction with serum allergy testing.
