Could the vet have been wrong about his diagnosis?

Now that we have been testing Fenner, his BG is within range, and we haven't been giving him insulin for a few days, I'm wondering if he was diagnosed incorrectly to begin with. The vet told us he had a UTI as well as diabetes. Could the UTI have caused his BG to spike, making the vet think it was diabetes when all along it was a simple UTI? He was put on an antibiotic for the UTI after diagnosis.
 
Hi Jill,
Did you change his diet after the diagnosis to lo-carb wet food or change his diet at all? I noted on spreadsheet that you're feeding Wellness, that's a very good lo-carb food. A food change can sometimes be enough to bring them down.

Stress is often a factor in blood glucose levels while at the vet. I have seen a 200 pt difference between what it was at vet's and home within 2 hours. It's possible that not feeling well from the UTI made that effect worse and yes, being ill can raise BG levels because illness is a stressor on the body.

It looks like you're doing very well then - aren't you glad you started home testing right away! This is another reason why home-testing is so crucial. Good job!

We need an applause smiley!!!
 
Awsome job with home testing and figuring this out so fast....
I believe my Beans # were higher during her first curve at the vet. She was dx with bgs in the 420 range and her first curve was over 500, but the night I got her home, she was peeeing around the house, small amounts...back to the vet the very next day and they said she had uti.... He increased the dose from 1u to 2u that day... But I didnt because of this site and being a bit scared to do that.
But I did not start home testing for about 10 days later...

GREAT CATCH :thumbup
 
Infection/inflammation can raise BG levels. It may have been that Fenner is vulnerable to diabetes and the UTI was all that was needed to push numbers over the edge. If you were feeding the way most of us fed pre-diabetes, food may have contributed, as well.
 
Hello all! It's Bruce typing this message (Jill's husband). I'm truly starting to believe that Fenner never really had diabetes, rather a combo of UTI & "at the vet" anxiety. I spoke with our vet today, and suggested meeting with him in person to discuss Fenner - which he agreed to. He was actually rather cooperative on the phone, and hopefully will be when we meet with him. We plan on taking our spreadsheet along to show him the numbers from all the testing.

My question is about the glucose meters. He didn't object to our use of the meter, but agreed that it's a good way to trend Fenner's numbers. However, he said that the accuracy is questionable due to the fact that the meter is designed for humans. Is there any documentation that anyone knows of that might show that a "human" glucose meter is on par with the equipment the vets use? I'm not looking to walk in waving paperwork saying "See...you're wrong!" - but I'd like to be armed with a little knowledge on the subject. He didn't seem to be concerned that we saw some low numbers when he was on insulin since "their equipment is designed for animals and reads higher".

Any info would be appreciated! Thanks again to everyone for all the help and support!
 
Here is some info I found:

Meters for animalsEdit
Some people prefer to buy animal validated meters, like these[31] [32], especially for canine patients. This page[33] presents the opinion of the developer of one animal-specific meter as to why human glucometers are not appropriate for use on animals. On the other hand, some recent testing[34] by volunteers from the FDMB found no significant difference in accuracy between the Abbott AlphaTrak and leading human glucometers, on feline blood.
Animal-specific systems are far more expensive than glucometers and test strips made for humans. A vial of 50 test strips for one model is $75. Alterations are made to the human test strips to produce a result.

When the system appeared in 2004, the FreeStyle meter was offered with the altered strips. Those animal-validated strips are no longer available, but caregivers can purchase/use standard FreeStyle test strips in that meter. The currently offered meter with animal-validated strips is the EasyGluco[35]. You cannot use the EasyGluco strips in the FreeStyle meter. Many from the Canine Diabetes Message Board[36] have tried the animal-validated strips; no one except the person mentioned in link below was able to obtain consistent, reliable results.

In March, 2006, Abbott began marketing its AlphaTrak[37] animal-validated glucometer. It basically operates similarly to those above, with the validation process being accomplished through obtaining blood glucose test results over a period of time from dogs and cats and validating through averages of them[38] as compared to Antech Laboratories' results. Over 200 dogs and 200 cats were tested to validate the AlphaTrak meter--in each group, only slightly more than 50 were diabetes patients.

In the AlphaTrak system, it's the meter which is validated; the two systems above are validated through the test strips. Knowing that the validation was applied to the meter and not the strips, it's interesting to note that Abbott's latest glucometer for people, the FreeStyle Freedom described below, also is able to use the tiny 0.3 microliter blood sample as well. All blood testing was with venous, not capillary, blood[39].

These threads from FDMB offer both a graphed[40] and a numerical[41] comparison of the Abbott AlphaTrak glucometer for pets against some of the more popular meters made for humans.

You can compare the variance between your home meter and the vet's lab testing easily enough. Take your meter with you when vet blood tests are being done. By using a drop of the same blood sample, you will be able to see how much difference (if any) there is between your vet's equipment and your home meter[42]. Regardless of the brand, most find their glucometer is quite accurate when compared this way[43]. (Note that some vets, when testing blood glucose and not also other blood values, use a human glucometer instead of their lab equipment.)


My opinion:
I don't think we would argue that human meters are more accurate than pet meters. We think pet meters are ridiculously expensive as are the strips and not always locally available. Many of us have taken our human meters into the vet's office and tested the same drop of blood with both meters and they are a few numbers apart. Since we are looking at trends and patterns and ranges, a few numbers difference is not an issue. Whether Fenner tests at 100 or 117, he is still too low for insulin and in normal numbers. That's why we say non diabetic cats off insulin can range from 40 -120. For some cats, 40 is normal. For others, 85 is normal. The meter allows you to figure out your cat and react.

Not sure if that helps.....
 
As a Newbie, I have recently done a lot of research.

Here is a link to an article from Cornell http://www.vet.cornell.edu/fhc/brochures/diabetes.html. It references the Sugarcats website...had link showing how to test at home, and they reference using human glucometers.

My vet thought I needed a cat meter, so he ordered me iPet, which I used, and I also used Relion (Walmart). I took both the iPet and the Relion to vet visits, and had the vet test with his Alphatrak and the iPet and the Relion human meter. The Relion was closer to his Alphatrak than the iPet, and only off by 20 points. So, he's fine with me using the Relion.

I'm sure you will get a lot more information, much more detailed. But, it only took my vet testing my meter with his.....course, he's a good vet, too.
 
Wow! Thank you!! That's quite the response!! :lol:

Although some of it is a bit over my head, I get the bulk of it....and it does prove useful! I basically want our vet to understand why we, using a "human" glucometer, were still concerned about seeing low numbers a few times - and to justify why we stopped with insulin injections. When Fenner was diagnosed with diabetes his number (if memory serves correctly) was 356. That's a far cry from the 80 - 117ish readings we've been getting the last few days! So, even if there's a discrepancy in meter accuracy (ours vs: theirs), it isn't that great! My point being that if we read 85 at home, and maybe their meter would read 95 - so what?? It's still a perfect range to be in!

We can tell a big difference in Fenner as well. He has put a bit of weight back on, his fur feels much better, and he just seems "like himself" again! Last night he even chased one of the other cats to play...it's been awhile since we've seen that out of him! It makes us quite happy...and I feel that (with a lot help of the forums) we've made some great decisions for his health!

Thank you again for your response! It certainly is of value!
Regards,
Bruce
 
I also recommend taking your meter in with you. Test the same poke with the vet's meter and yours. As long as there isn't some crazy 200 point difference there is no reason for the vet to believe that good numbers on your meter wouldn't translate to good numbers on his meter.

Once we tested our meter to the vet's, they never did another stand alone BG test on Smokey again. They only run it at the office when doing other blood work.
