So frustrating: Luna's lab results are back - negative!
Well, on the first sight, this sounds like good news, but it isn't. As reported here, my vet sent Luna's urine sample to a lab for a urinalysis, and we were hoping to find e.coli or another kind of bacteria to give her a systematic treatment - but there's nothing.
My vet has just called me because she's been in her office this weekend and saw the lab has faxed the results on Saturday - earlier than expected. So she called me to give me the news.
The entire thing is so confusing and frustrating. One option could be that there HAVE BEEN an bacterial infection, but at the time I got the urine sample, the Lasix has already flushed out all the germs. Since antibiotics always help Luna (at least temporarily), there must be some kind of bacterial infection, right? A previous urinalysis two weeks ago already ruled out crystals, but they found some blood cells and bladder tissue cells, but no cells coming from the kidneys (which is good according to my vet, because it means the kidneys are most likely not affected).
My vet mentioned the possibility of a bladder polyp, even though she thinks it's unlikely, as in 99%, cats with symptoms like Luna's have a cystitis caused by bacteria. However, you won't find out about the polyp unless you open her bladder surgically or x-ray her with the help of a contrast medium. But my vet still thinks it's unlikely that Luna has that, or - even worse - a tumor.
Anyway, surgery or this kind of x-ray shot is an ordeal my vet would like to avoid for Luna, and she would prefer to try the e.coli immunization (as she thinks the symptoms are still typical for that).
Also, we will take blood from Luna tomorrow, I want to be sure about her kidneys etc., especially as her fur isn't looking good lately.
I'm very nervous and worried about Luna, and I would have definitely prefered a positive e.coli test result.
Please keep my Luna in your thoughts. I love her so very much, and I hope she's not seriously ill!
