Glucose testing with AlphaTrak #file-notice


Hello, can anyone give me advice about using the AlphaTrak glucometer?  I was told to use the cat code for testing Stubby, but I am not sure how to use the results or how accurate they may be.  Has anyone else tried these?

Did you miss the answer to your original question? Re: Glucose testing with AlphaTrak ( - the short answer is there's no way to correlate glucose readings to insulin readings in horses.  Insulin is the number you need to be monitoring, not glucose.


Hi, Toni.
The manufacturer is the source of the most accurate information about the use of your glucometer. Here is the link:
Remember that Stubby is not like a human diabetic. The critical hormone to control is insulin, not blood sugar. We do use the glucose value for a variety of purposes, as outlined in the answer to your question.

I found your case history misfiled in our Case History sub-group. 

I also found your photo album:

Would you please copy and paste both links into your automatic signature. Here's how:
1. Open up your subscription page at this link: 
2. Scroll down to the signature box and paste the link to your folder, not the case history itself, right below your  signature. Add a space or return after the Url to make it clickable. It will turn blue. Do the same for the link to your Photo Album.
3. Scroll to the bottom of the same page and SAVE!

Let us know if you run into any problems.

Thanks Cass for finding the Case History.  The folder that it's in should be the link added to the signature though (I've moved it to the folder that was created but was empty), so Toni use this link in your signature: 

Now that Cass has found the CH and photos the first thing that jumps out at me is that Stubby is very overweight.  The one x-ray you shared shows a long toe and next to no sole so she needs a diet change ASAP.  

Are you actually weighing the hay she's being fed at this point?  If so, 2lbs is much too little and feeding too little can cause other issues.  If you want her to lose weight she needs to be eating 2% of ideal weight or 1.5% of current weight whichever is greater and that amount should include both hay and any concentrates.  For an ideal weight of 250 she should be eating 5lbs per day.  You may need to tweak that amount based on how much she is losing (or isn't losing) but again, feeding less than that is not the answer.

As outlined in your welcome letter at this point she should be eating soaked hay until you can get it tested and you can use either Triple Crown Timothy Balance Cubes (fed at a 3:4 ratio to hay) or rinsed, soaked, rinsed beet pulp for a carrier for supplements.  We do not recommend Heiro here as it's not been found to be useful.

I also would not let her on pasture at all unless she's wearing a closed muzzle (the hole in the bottom taped up). Do not force her to exercise at this point either as she needs some corrective trimming done and time for her feet to grow out before exercise is added in.  If you could add a full set of pictures as outlined in the Wiki: that would be very helpful. Is she in boots?  If not you may want to get her in some so she can be more comfortable.


Hello, I guess I did miss the original answer.  I will go back and put everything in the correct format, thank you for the instructions on how to do that.  Stubby's feet were trimmed after the xrays were taken.  The vet called my farrier and told him what to do and hopefully it was done correctly.  I will redo the after trimming hoof pictures, but I haven't had any xrays done since the trim.  Stubby is overweight but she is also somewhat ribby.  Most of her weight seems to be in her abdomen.  When I first brought her home, friends kept asking me if she was pregnant, lol.  Is that due to IR?  She is thinner now than she was a year or so ago!  I have tried a grazing muzzle in the past, but she is a master at removing muzzles and halters and fly masks.  Is there a trick to keeping them from scraping the muzzle off?  She can even untie her lead rope if it isn't tied above her reach.  I had hoped I could find a way to keep track of glucose and insulin myself, since my vet has been less than helpful.  I bought her some boots, but they did not fit so I am still shopping.
