I know you mentioned back awhile about potentially testing for acro/IAA. Did you decide on that yet?
There are a variety of reasons why his globulin, neutrophils, and WBCs might be high but often it has to do with infection or inflammation. I’m not really worried about the globulin as it is barely elevated and labs are always just a snapshot in time but it’s definitely something to watch. He’s not had any steroids, right? Sometimes stress can cause the adrenals to release corticosteroids which can increase the neutrophils and band neutrophils.
The creatinine is a little higher than I’d like to see it. While it is in the “normal” range, we usually would do a little more looking at some other things when it gets above 1.6. Yes, it is a number that can go up and down a bit and there are other reasons why creatinine might be elevated other than the kidneys. His BUN is normal which is good but sometimes we see a lower urine specific gravity (below 1.040) and a creatinine above 1.6 and that throws up a red flag to me that a kitty “might” have very early chronic kidney disease. I’m not saying this applies to Gizmo at all and occasionally, I see a creatinine at 1.9 or so and the next test, it is back down below 1.6. The other things is that in very large cats, we might see a higher creatinine but since his creatinine was 1.6 earlier this year, than I don’t think his size is a factor.
Unfortunately, we don’t have a USG here to see what it looks like. What you can do is do a free catch of urine of the very first pee of the day and run it to the vet. They should have a refractometer and be able to run the USG without sending it to the lab. If the USG is above 1.040 in the first sample of the day, then he is concentrating his urine and the creatinine is a little elevated for some other reason. If it’s below 1.040, then he isn’t concentrating his urine as he should be. Also remember USG can vary during the day so if you take his second or third pee of the day in, it wouldn’t surprise me if it’s lower and I wouldn’t consider it to be the best indication of whether there is any early kidney issue or not. Sad to say, but many vets miss this very, very early warning sign. Again, I’m not saying this applies to Gizmo but if it were my cat, I’d have it checked out.
BTW, IDEXX lab usually includes an SDMA test as standard with their superchem. The SDMA along with the creatinine is a really good indicator of kidney function. However, if your vet doesn’t use IDEXX, then it doesn’t really matter.
Other than the above and the T4, which we already discussed, I don’t see anything of concern. Glad to see his ALP came down.
I’m not really sure why vets run “mini labs”. For me, I always have the superchem and cbc done because you see so much more than just with a few tests here and there. And I always have a urinalysis done annually.
Please let me know if you have any questions.
