Update on my girl: the vet sent me her lab results today!
BUN is down from 51 in October to 30 now; the ideal range is 7-27 so a smidge high, but much improved. And her creatinine levels have stayed the same, 0.8 in the last 3 tests where 0.5-1.8 is normal. Which is great news, it means no kidney issue :-D
ALT is still high at 185, but essentially unchanged from her last two visits. For some reason they didn't run an ALP test, though, which REALLY bugs me because I paid for it! Those numbers were super super high before, and I'd really have liked an update >:-( But everything else is normal, so it looks like liver
inflammation but not
disease
Hematocrit went from 36.7 to 24.7. The ideal is 37.3 - 61.7, so definitely anemic! Her red blood cell count dropped from 5.2 to 3.56, which means that the problem is blood loss and not dietary. Her Reticulocytes (new red blood cells) is high at 132.1, though, which it SHOULD be high when her RBC is low! So that means no bone marrow issues
All combined, she has probably had blood in her stool for months that I couldn't see. Which is probably best case scenario, since the Prednisone likely caused it and now it can heal.
We're still dealing with intestinal inflammation, though. Yesterday and today she had bright orange diarrhea (implying poor bile production), she's had very little appetite, and getting pills in her has been... rough. The only food she's had has been boiled chicken, rice, and pill pockets, she's taking Metronidazole (antibiotic) and FortiFlora (probiotic) twice daily! So I don't think there's anything more I can do but stay the course and hope for the best!
