Probably a frisky kitty has batted it under some furniture! 
Same for me. When I was still using the AT2 I ordered it from Countryside Pet through amazon.com, as they sell _some_ but not all, of their products on amazon as well. But I just checked and it doesn't look like the control solution is there, but it is through their direct website: http://www.countrysidepet.com/alphatrak-2-control-solution/ But one thing to note. For products on their own website vs Amazon, the prices can be different! Makes no sense to me, but it is true. And one isn't always cheaper. A while back, the meter was cheaper on amazon from Countryside, but the strips were cheaper on their own website, so check both.I order from Countryside vet. Reliable and fast shipping. I get my strips from them in 2 days. I buy 2 boxes which is free shipping.

It is supposed to confirm that your meter is working correctly. On the side of the control solution bottle there is a range printed...I don't have it in front of me, but let's say it is 130-145 or something. You put a drop of control solution on the test strip, just like you would blood, and make sure that it reads in the range that is specified. If so, you know you are good.

One other thing to think about. They currently have the AT2 kit on sale through amazon for $54.50 (http://www.amazon.com/AlphaTRAK-Blood-Glucose-Monitoring-System/dp/B007Z0XULY/ref=sr_1_1?m=A2U9QJC4OCXBWF&s=merchant-items&ie=UTF8&qid=1446379522&sr=1-1&refinements=p_4:Abbott), on their own website it is for $59.97, and it comes with 25 strips and 1 bottle of solution (instead of 2), and all of the usual stuff like lancets, lancing pen, etc. I have always liked to have a spare meter, just in case. So you could always think about getting another kit to get you everything, including a "spare" meter. Just a thought. Good luck!
I would not do that with different manufacturer's meters. There are different ways to measure BGAnd if you are wanting to compare a specific human meter with the AT2, you can test the control solution with both meters a few times to get a sense of the variability between them.
But as I said some meters use different measurment methods and thus I would not expect control solutions to perform the say. What proof do you have? The manufacturers say only use their control solution?Control solutions have a given concentration. You would expect similar results within meter and a given relationship between a pair of meters when comparing them, such that
meter A = weight* Meter B +/1 constant +/- error variance.
Thanks, I'll check their website.I order from Countryside vet. Reliable and fast shipping. I get my strips from them in 2 days. I buy 2 boxes which is free shipping.
I've been thinking about a getting a spare meter so will check the Amazon sale. That's where I got my present meter. Thanks.Same for me.

Do you keep record of the difference between the control solution readings with the first strip readings and factor that in to the BG reading? If so how do you do it? I've been checking the control strips with the range on the test strip container only to make sure it is within proper range.It is recommended that control solution be used to check each new package of test strips to ensure they are reading within the specified range as well as to check the meter. Every vial of strips can read a smidge higher or lower so I always use the control solution on the first strip as a base line in case I notice slightly lower or higher numbers.
That's exactly what the control solution is for.I've been checking the control strips with the range on the test strip container only to make sure it is within proper range.
I took a peek at your spreadsheet.I simply use it as a gauge so if I notice a few points up/down in readings with a new vial and the control test was a few points higher/lower than the previous vial, I know it's likely just strip variance and not a change in my cat's condition.
Agreed but just ot clarify, the point or two higher or lower using our mmols is much more significant than a few points using your scale of measure.One can't tell anything about a cat's condition from that. A few points higher or lower become a moot point especially when kitty is consistently throwing numbers in the 300s and 400s..
Yes, but only because of the numeric systems themselves. That's all.Agreed but just ot clarify, the point or two higher or lower using our mmols is much more significant than a few points using your scale of measure.
Number turned around...it's 1 mmol/dL - 18.018 mg/Ld1 mg/dL = 18.018018 mmol/L
Oops! Thank you very much for the correction!Number turned around...it's 1 mmol/dL - 18.018 mg/Ld
Typo!I've always seen millimoles per liter abbreviated as mmol/L and milligrams per deciliter abbreviated as mg/dL...
