Just got back from a visit to the dermatologist and sent off some blood to
Heska for testing. I also asked the dermatologist about VARL but she thinks Heska has more repeatable results.
For anyone who's curious about pricing, going with either VARL or Heska would cost around $315.
In the meantime, Ruby's is switching to a home-cooked vegetarian diet for 3 weeks (along with half tablet of Zyrtec twice a day) to see if she responds any better so she can restart her food challege. I'd be happy to post the recipe if anyone is interested but it does not look like it will be at all tasty...
Thanks again for all the information, everyone! I feel like Ruby's finally on the right track to getting better
