I knew this was going to come up, and wasn't going to say anything, but this has been my experience: I've been taking ferret blood sugars at home, from the arm vein, for 4 or 5 years now. At the time I started I got the same meter they were using at the vet clinic, an Accu Check Active. I don't recommend it because it requires more blood than the newer meters. However, since I have gotten it, we have made it a habit of about every 6 months checking it against the all the new meters the clinic has gotten including the species specific meter they now use and against actual lab testings. It is always within about 3 or 4 points. The point is, as Sukie recommended, regardless of which meter you get, test it against the glucometer they are using in the clinic, but also, just for additional verification, I'd suggest checking against a lab test as well. If you are doing the 'pad stick' as opposed to an actual blood draw, you will probably have to have your vet help you with that. One stick won't give you enough blood for all those tests and different sticks will give you different readings. Even with a blood draw, the longer the blood sits in the syringe, and I find this change starts pretty quickly, the wider range of numbers you are going to get. So ideally you will draw the blood, and start all three tests as close to instantly as you can. And another warning. Test strips are very sensitive to temperature extremes and time. The date on them seems to be an end date and arbitrary. I find my strips even properly housed only last about 30-45 days. Time or temperature either one can cause some really weird and really wrong readings. Most meters have a testing solution to check and make sure your meter is functioning within a set range. We don't want a 'range', we want legitimate numbers so if you have any doubts, at any time, check it against the clinic's. Again, just my experience.
