@renaultf1:
I'm so sorry to hear about Tayda's test strip.
Another thought…do you have any critical care vets in your area. We have one practice that deals with only cancer, kidney, and other special cases. They aren't a regular practice, only disease diagnosis and treatment.
I know 2 hrs is a bit of a drive, but I would seriously consider going to Angell or Tufts at least for the initial diagnosis...especially since it doesn't sound like any of these vets have any idea about even the blood gas aspect. I have so many friends who sing the praises of Angell...and Tufts.
Diagnosis, if Fanconi, is pretty straight forward… if they are spilling sugar in their urine, but not high blood sugar in bloodwork, then it is Fanconi... Blood gases are then needed to determine the course of treatment using the protocol. Again, I would take the protocol before hand to the Vet you were seeing on Wednesday. I would also continue to strip test daily. As was already stated they can spill one day and not the next when you catch it early. Happened to a good friend of mine with his dog... he was positive for sugar in the urine one day and then the next 2, none, the following day, he positive for sugar in the urine again. That said, a full blood panel is needed also along with the blood gases.
