Hi Bo's mom (dad?),
I took a look at Bo's ss and it looks like he was diagnosed in Sept 2010, you were using Lantus, you test occasionally using a Relion meter, and you are feeding canned MD, and you have had a week or so of 1x/day normal non-diabetic numbers, and no insulin given this past week, until this AM by the vet. Am I close?
It looks like Bo is trying to go OTJ! (off the Juice). Lucky you !
A lot of us have seen that the "curve" that the vet does is not a good representation of real life for our kitties. They are just so scared and nervous that their blood glucose numbers are higher than they are at home.
I also was surprised that they only took 3 readings (?). My vet did something similar and charged me $90. At home I could have seen a much more complete picture by testing every hour or two, and seen a much more complete curve (for about $2)
A "curve" occurs as a result of giving insulin, and then testing every 2 hours or so, watching how the BG readings graph out. Usually they are looking for a U -shaped curve, high near the shot, dropping mid day, and then rising again before the next shot, so they can see what the insulin is doing to their blood glucose level.
I'm sorry I cant help you with the normal duration of Lantus because I haven't used it, but many here can. I know it is usually shot on a 12hr schedule, so you "should be" past the peak action of the insulin. You always have the power to test him anytime and know whether he is too low- thats the beauty of home testing!
If you continue to get a 2-3 weeks of non diabetic numbers, you could satisfy your vet by having her run a fructosamine blood test, which gives them an approximate average of the blood glucose over the previous 2 weeks.
As for tonight, what's his readings now?
