WAY different. 100 pts. less. Will be shopping for a new monitor now. I am not pleased.
ReliOn Micro reading different from Vets.

What meter was the vet using? A pet meter (Alpha Trak) will read higher than a human meter. That is why there are different dose decrease cut-off points for human and pet meters on the forum. The pet meter and the human meter can't really be compared.
The difference is also exponential. The higher the number, the greater the difference.

Hi Viggo's Mom
Here is a helpful post written by Larry which explains how the difference in the way that glucose is distributed in the blood between cats and humans affects the measurements seen when using a human glucometer to measure.

From the above post:
Human meters typically read lower than pet meters because the distribution of glucose in the cellular and liquid constituents between humans and cats is different:
Blood Glucose Meter for Cats
Facts:
Blood has two constituents, the red and white blood cells and the liquid (serum). Blood plasma is blood serum without the clotting factor
The blood glucose value obtained via laboratory analysis is the glucose level in the serum/plasma constituents of blood.
The glucose is in both the serum and red-blood cells (RBC) themselves. However, the distribution of glucose is different between humans and cats (and dogs too)1
In Humans 58% is in plasma/serum and 42% in RBCs. In cats 93% is in plasma/serum and 7% in RBCs
The point-of-use blood glucose meters (the ones we use at home) all use whole blood.2 However, what specific blood glucose they measure varies with the manufacturer. Some manufacturers only measure the glucose in the serum/plasma. Others lyse (disrupt the cell walls of the RBCs) and thus mix the glucose that was in the RBC into the liquid and thus measure total glucose. The meters then correct/adjust the reading to be equivalent to human blood plasma. [NOTE: this is the reason why human meters display a lower reading for cat blood! - Mogs]
[...]
Since the glucose distribution is different in humans and cats [...] the resulting BG valve obtained from the human meters will be different that lab values and animal-calibrated meters. Also, some manufacturer's meters will be much different that lab values for animals depending upon which method (lyse cells or only use plasma/serum) they use to measure glucose.
Animal calibrated meters correct the value to be equivalent to lab values.
[Emphasis mine]
To monitor BG safely you need to use the reference range appropriate to your meter type. For cat BG measurements using a human meter FDMB uses 50-120mg/dL (US), 2.8 - 6.7mmol/L (international) as the normal blood glucose range for a cat not on insulin (i.e. the normoglycaemic range for a healthy cat - range derived from academic publications on feline diabetes).
