So Jordan went yesterday to have his ionized calcium level rechecked. I had them get his weight, last time it was 14 lbs, this time 12.4 lbs. I was concerned, but the vet said if they didn't use the same scale that could be why. I personally don't get that all the tests that have been done have differnt "nomal" ranges, but the latest is that the top end of normal is 5.4, his was 6.4. I'm not all that supprised, just frustrated. My vet is part of a 5 vet practice and has talked to the other 4 vets, and the vet at the emergancy place that did his ultra sound. None of them have any true idea of what's going on, but here's the latest plan. No need to do exploritory at this point because the ultra sound was totally normal and they feel they would find nothing (I'm thankful for that). There is still a possibility that he has intestinal lymphoma in very early stages. It is also possible he has cancer, but is too small to show on x-rays and they can't just go exploring his whole body with no idea where to look. So Thursday he is going to have a urinalysis to rule out any kidney disease (and I think something else). If those tests are normal the vet want to treat as though he has idopathing hypercalcimia. Sounds easy, but the standard treatment is prednisone, which the vet dosen't want to do incase he does have cancer or lymphoma because I have expressed intrest in chemo. So he has to do some research, and once again none of the vets in that practice have any experience with treating idopathic hypercalcimia. Depending on the test results I may ask if it would be worth taking him to an internal medicine specialist. I was supposed to see one when he had the ultra sound, but unfortunatly that e-vet is currently without an internal medicine specialist. So, we've ruled out, thyroid, parathyroid, a bone disease, Lymphoma (for now). Basicly $1,300 and no answers. He's been doing OK, still not 100% Jordan, but he's eating a fair amount. Me, I'm just frustrated and afraid I'm going to lose him without ever having a diagnosis.
