[quote1304350193=Igmuska] Usually these RAST and ELISA blood allergy tests are sent out to labs, so most Vets can do this for you. Just a note, most of the blood based allergy tests were developed for humans, therefore there is a high account of false positives. It is a good idea for a general idea of allergenic triggers, but not to be taken definitively. [/quote1304350193] Thank you Igmuska.
