Are you keeping the Alpha or returning it? I ask because I know people that on a daily basis test with a human meter but occasionally test with the Alpha when supplying numbers for their vet. Another idea is to take your meter with you to your next vet visits and compare the results done on the same sample. That way your vet can see how they differ. My vet had never seen the meter I used but we tested using both and he looks at my spreadsheets that I send him. I am so glad I didn't start with the Alpha as I am having to test so much it would add a lot to the cost of treating Max and in my opinion is an unnecessary expense. The last vet visit we tested using the alpha in his office, I tested before going with my meter at home and got the lab results and they were not very different.
