Hi Alison,
I bought a new glucometer, the Accu-Check Aviva and test strips for 
people (where do I get test strips for horses?). I bought test 
solutions for it and my old Accu-Check Active. At first the Active 
tested a consistent 20 points higher than the new Aviva using the 
same blood sample then the low battery light came on the Active. I 
put in a new battery and now after 6 or more tests they both give the 
same reading using the same blood and both give the correct readings 
when tested with their test solutions......so the meters are okay. My 
3 geldings are fed alfalfa only. 21, 15 & 10 yo. The 10yo gets 4lbs 
grain 5-6 times a week. Their morning alfalfa is always gone by 8am 
so I have been testing them after 6 hrs of fasting at 2-3pm. All 3 
get readings of 60-70 on both meters. I have not done a "correct" 
glucose curve yet but here are the readings I have taken in 2007. Two 
readings minutes apart was to see if the meter was going to be 
consistent. Two readings listed at the same time means I used both meters.

1-07 fed alfalfa at 2:30, tested after hay was gone at 3:47 = 78, 
tested at 3:55 = 73
1-08 fed alfalfa at 2:30, tested after hay was gone at 4:36 = 67, 
tested at 4:47 = 68
1-09 fed alfalfa at 1:00, tested at 1:00 = 62, tested at 2:26 = 61, 
tested at 3:13 = 84
1-10 fed alfalfa at 2:30, tested at 3:52 = 86
1-11 fed 4lbs grain at 1:40, tested at 1:48 = 70, tested at 1:51 = 
77, tested at 2:53 = 82&83, tested at 3:44 = 104, tested at 4:01 = 80&82
1-13 fed 4lbs grain at 10:40am, tested at 10:47 = 62, tested at 1:02 
= 124, tested at 1:04 = 127, tested at 3:06 = 60
1-15 fed alfalfa at 2:30, tested at 5:07 = 72
1-19 fed 4lbs grain at 9:00am, tested at 9:01 = 57, trimmed hooves 
and took 2 hr ride, tested at 2:17pm = 84
1-20 no food tested at 2:16 = 72&72
1-21 no food tested at 1:22 = 74
1-23 fed 4lbs grain at 10:30am, tested at 10:36 = 67, tested at 
12:17pm = 106, tested at 1:21 = 108, had to leave
1-24 fed 4lbs grain at 1:00pm, no test, tested at 1:44 = 85, tested 
at 2:29 = 103, tested at 3:14 = 106, tested at 3:48 = 98, had to leave
1-28 fed 4lbs grain at 1:00pm, no test, took a 2 hr ride, tested at 
4:22 = 71, tested at 4:24 = 82

Not very scientific data (I will get better) but what do you think so far?
