Lab blood work and home test difference

Hi - might be an obvious question, but when you get the blood work back from the lab when they do a complete profile and it lists the glucose amount - what is the difference between that and the home testing amount?
The vet did not test her blood on the spot in other words. They sent off a complete blood check to see if everything else was okay and it lists the glucose. hope this makes sense
 
so the glucose reading they are giving is the same number they would provide if they just took blood from her ear in the office right?
 
So they did a fructosamine test? It's an average over the past few weeks. It is a more accurate way of diagnosing diabetes than one ear poke in a vet's office, because of vet stress.
 
Lab results don't usually come out exactly the same as the glucometer results. When they send it out to the lab, their sample processing protocols and assays are different than how the monitors work.

so, would the lab results be more accurate (subtracting for stress) ?? Her glucose when I got her from the humane society was about 470. It showed 343 on the blood work
 
i am waiting on the insulin to arrive. it requires a signature. might have to find a local supplier instead.
 
well, there's a big improvement since she left the humane society, but obviously not good enough. Boy I hope this works. She is cute and I am trying my best.
 
CJ's glucose levels are always elevated at the vet due to stress. My vet and I go by the results I get from home testing.
 
The result from the lab is likely to be higher than home glucose tests with a human glucometer, in part because they measure in different values. Its kind of like measuring temperature in Celsius or Fahrenheit.
Additionally, cat's glucose tends to go up under vet stress, from 100-180 mg/dL in some cats.
 
I would say it depends on your individual meter. The one I have, I've recently been able to check against lab results on two separate occasions (I'm using a ReliOn Confirm at home) and it reads within 5 points of the lab. However, the reference range for normal for the lab is higher than we use for human glucometers...the lab range for normal is 72-175. That would seem to indicate that my meter maybe reads a little high as a reading of 96 at the lab is in the lower half of normal range, but a reading of 93 (which I got on my meter at the same time) is pretty much in the middle of the normal range for a human glucometer. But the numbers are close enough that I'm not worried about the reliability of my meter. However, that kind of result would only necessarily be true for the individual meter that I'm using, so results are going to vary but I just wanted to make the point that sometimes, with some meters, there really is very little difference in the numbers you get compared to the lab. If you get the opportunity at a future blood work appointment, it would be worth taking your meter along and getting a reading from the same sample that is going to be sent to the lab - that would likely give you a better idea of how great the difference is. :)
