Default Animal Validated Meters???

Did any of you know that there's a difference between the GlucoPet and GlucoVet meters?

http://www.animaldiabetes.com/glucopet

GlucoPet

http://www.animaldiabetes.com/glucovet

GlucoVet

"GlucoVet is recommended for Veterinarians and customers with medium and/or large animals. More accurate readings than the GlucoPet, for glucose values of 300 mg/dL or higher."

From what's written on the GlucoVet page, the GlucoPet meter must be less accurate in interpreting higher readings than the GlucoPet meter. The GlucoPet and GlucoVet meters have separate strips also:

I knew there was a difference, I use the Glucopet,
At times my glucopet has gotten reading in the 500's but when its at 600 i believe it just says HI, thank goodness I hardly ever see that.

Can you explain about the adding 100 points to a FreeStyle? Many people were using them and they weren't adding 100 points to their readings that I heard of. Many people take their meters with them when blood tests are done and use some of the same sample to see how their meters compare to what the lab says. Do you have a link about this you can share?

http://www.bddiabetes.com/us/main.aspx?cat=1&id=404

BD Diabetes, Dr. Greco:

"Q: Do I have to recalibrate a "people" glucometer for my pet?
A: If you have a dog, it may not be necessary to recalibrate. Studies have shown that results from blood glucose meters designed for people compare reasonably well with laboratory values in dogs. However, some blood glucose meters tend to be more accurate for animals than others. Ask your veterinarian to recommend a product that would serve well for you and your pet."

http://www.felinediabetes.com/phorum....php?15,327824

Most of those testing at the Feline Diabetes Board are using meters designed for people. They did some comparisions when Abbott's AlphaTrak was new. Their consensus was that they didn't find the animal validated meter to be any better than the ones they were currently using. They found AlphaTrak to be very much like FreeStyle. Here are the comparison graphs they did:


If you have a link where it's suggested to add 100 points to a meter, I think we'd all be interested.

Hi,
I use a Medisense Optium meter that was the cheapest and most basic model here in Australia. I have had it compared to the local vet's meter and also the specialist's meter and also lab results and all of the readings have been under a point (multilpy by 18.02 for USA). If my meter showed 4.1 the lab was 4.4 and specialist and vet meter was 4.2. I understand that some really high readings will be way off but I am really happy with this basic model and my aim is to keep Buddy in a good range anyway (Fingers crossed).

hey ya'll,
I have to compare my freestyle freedom human meter to my Alphatrak dog meter. Will post today and all week as IMS Dr Stone wants me to compare for a week. So far the higher her BGs are the more of a difference between the meters m(way over 100 ) The freestyle of course is much lower Pebbles for some reason is on the high on the meter. Don't know whether it was because she yelped last night when I injected. Did I hit a muscle? I pulled needle out in injected farther up on her scruff. Today she is really high. Will keep you posted on the differences I found

Default Re: Animal Validated Meters???

thats why i got the glucopet, i did not want to be adding points, plus when i compared the prices of the strips at walmart for the other meters it seems they were all in the 45.00 to 55.00 range, so i figure I'm paying the same

I will go and check where I got the info.

I took Niki to the vet before we left I got a 89, 1 hr later at vet she was at 129, the vet did take her blood, and did the meter, I took it with me, she said maybe add 20 pts to it, maybe not and wanted the info on the Glucovet, I don't know if they bought one yet.

She said the meter gave a better reading. I think the glucopet is darn near the correct reading as when Niki is low I know it and take her BG and she is usually low, when she is leaking pee I do BG again and get the high of 250 or more, I guess it all depends on what you are used to using.

Plus I like the fact that the Glucopet lady "Karen" is very nice to work with, about a year ago a bottle of strips kept getting error messages, so I called her, and she sent me a new bottle of strips, so I appreciate that, especially with how much strips cost.

I test Niki quite frequently so I think I go thru 100 strips in about 2 months more or less

Regardless of the meter you use, it's wrong and dangerous for anyone to just say to add 100 points to the reading you're getting from it. That's like saying use 30 units of insulin twice a day regardless of the size of the patient and his/her medical condition. 30 units twice daily would be fatal for some, not enough for others, and would be fine for some. Blanket statements like this can harm or kill.

We have many human meters on the market--the one thing they have in common is that they must meet the minimum FDA requirements for a glucometer or they won't be on the market, because they won't get FDA approval.

http://diabetesindogs.wikia.com/wiki...Meter_Accuracy

http://www.fda.gov/cdrh/ode/gluc.html

Glucometer standards for human meters

The standard is over 20 years old and needs to be updated, but there's some conformity made possible by it.

Veterinary medical devices such as glucometers for pets don't need to be FDA approved at all.

http://www.fda.gov/cvm/regofdevices.htm

The only way to determine how much difference there is between the meter you are using and a professional blood test is to do what you did--take the meter with you and use some of the same blood draw for a meter test.

Have personally seen many people take their meters to a vet visit and then come back and post on FDMB or CDMB with the difference between the professional blood test and their meter. I've never seen anyone post that their meters were off by 100 points on either board--most differences posted have been a lot smaller than that.

Never mind, I deleted it, we already went thru an issue with someone giving their dog 80 units of insulin a day on another board, i wasn't trying to cause any harm, remove what you wish

Dolly,

The problem isn't with what you posted, but with the statement someone else made about all human meters needing 100 points added to their readings. In order to say this and have it be fact, someone would need to have tested every human meter on the market against professional testing and find that every one of them was shy by 100 points.

It's not addressing any supposed inaccuracies at all, but creating them.

Let's say I have a dog who is running very low--possibly going into hypo. I take a bg test and I get a reading of 35 on the human meter. If I add 100 points to that, then even though I might be seeing physical signs of hypo, the dog is really reading 135. If I go by this, I shouldn't be concerned about seeing the human meter reading of 35 at all and the dog doesn't need any syrup.

If I have a dog whose human meter reading is 100 and I add 100 points to that, I now have 200 points--20 points over the renal threshold. I become concerned by this, even though I see no physical signs of hyperglycemia. I decide to use a bit of fast-acting insulin to bring the down from what appears to be over the renal threshold. Not long after I give the fast-acting insulin, I see physical signs of low blood sugar/hypo. And again, if I go by adding 100 points, I shouldn't believe these are signs of a low because the dog was over the renal threshold when I gave the fast-acting insulin.

These are hypothetical examples of what can happen if one blindly adds 100 points to a bg reading by a human meter. The only way to know how much difference there is between whatever meter you're using and a professional test is to do just what you did--to take your meter to the vet appointment and do a test with some of the blood draw.

You're not wrong at all--whoever came up with this idea is.

When I started home testing I got the Assencia Elite by Bayer for it's small amount of blood and the sipping action of the test strips. I took this meter to my vets when they curved Bogie and the first time I only compared his first draw and the alst draw of the day to their numbers. They had a lab analyzer. They drew blood, I used that blood in my meter (so arterial blood) and then I also did a lip prick. Their test showed 221, my meter with arterial blood showed 190 and 184 with the lip prick.

We did the same thing when I picked him up, their number was 250, my meter arterial blood was 242, lip prick was 215.

After that theya actually used my meter at the same time they did blood draws and kept track for me.

I've averaged the results and from 50 to 100 I add 40 points, from 100-200 it's like 30 points lower and in the 300's and up it's a bit more accurate being about 20-25 low. I don't know for sure how off it is over 350 or under 50 but I know ihe is too high or I know enough to watch him under 50.

I got a Glucopet at one point, used two containers of test strips and stopped using it as it was SO different than the Elite and it varied so much in the same range of numbers compared to the Elite. If the Glucopet said 200 and my meter said 180, the next time the Glucopet would be 220 but mine might say 260 so the way it varied I couldn't trust it. I didn't think I would get reading where the Elite was 40 low one time and in almost the same range the Elite would be 40 points HIGHER.

Now they are discontinuing my test strips so I am going to use a Contour and have enough Elite strips to compare to the Contour numbers.

I just want to say that if all of us used the same meter that we would get the same results and I (jmo) don't think that anyone has perfected the animal validated ones just yet. I am hopeful that they will some day though!

My vet now uses the AlphaTrak but uses arterial blood which I think is nuts! What draw blood every 2 hours when you could do a lip prick???

Anyway, I think we all have differing results with different meters and the only way to know for sure is to compare with your vet's numbers or have all blood tests sent to a lab for comparsion.
