Did any of you know that there's a difference between the GlucoPet and GlucoVet meters?
"GlucoVet is recommended for Veterinarians and customers with medium and/or large animals. More accurate readings than the GlucoPet, for glucose values of 300 mg/dL or higher."
From what's written on the GlucoVet page, the GlucoPet meter must be less accurate in interpreting higher readings than the GlucoPet meter. The GlucoPet and GlucoVet meters have separate strips also:

A recent study of six blood glucose meters reflects favorably on the OneTouch Ultra.
ACVIM 2008 Abstract
Evaluation of Six Portable Blood Glucose Meters in Dogs.
T. Cohen, R. Nelson, P. Kass, E. Feldman
School of Veterinary Medicine, University of California, Davis
The purpose of this study was to evaluate six portable blood glucose meters (PBGMs) - AlphaTrak, OneTouch, Elite XL, AccuChek, Precision, Contour - for use in dogs. One hundred fifty-eight venous blood samples were asayed for glucose using all PBGMs in randomized order and by a reference hexokinase method. Results from the PBGMs and reference hexokinase method (HM) were compared.
HM blood glucose concentrations ranged from 41 to 639 mg/dl. There was excellent correlation between PBGMs and HM results (table). Results were consistently low for 4 PBGMs compared with HM results. High and low results were common with the AlphaTrak. The difference in results between PBGMs and HM increased as blood glucose concentrations increased. Difference in results between PBGM and HM were significantly (p<0.0001) less for the AlphaTrak and OneTouch and significantly (p<0.01) higher for the Contour compared with other PBGMs. Problems with correct identification of hypoglycemia (<70 mg/dl), normoglycemia (70-120 mg/dl), and hyperglycemia (>200 mg/dl) varied between PBGMs (table).
Percent Incorrect from Reference Range
AlphaTrak -- 18
OneTouch -- 21
EliteXL -- 45
AccuChek -- 45
Precision -- 49
Contour -- 73
Results of this study support use of the AlphaTrak and OneTouch glucose meters based on significantly closer results with HM.

Just had a look at the owners booklets for both One Touch Ultra Mini (Johnson & Johnson/LifeScan) and FreeStyle Lite (Abbott) to see if there was a standard for "LO". Thought there had to be and that all manufacturers would need to be on the same page regarding such a serious message--it's below 20 mg/dl.
Standard for "LO" is 20 mg/dl.
One Touch Ultra Mini-Page 42
FreeStyle Lite-Page 20
The information is in the owners' booklet for your respective meter. Most to all of them can be viewed online at the manufacturer's website for your brand of meter if you've misplaced the booklet.
Looking at the same pages, the FreeStyle Lite says "HI" is over 500 mg/dl, while One Touch Ultra Mini says "HI" is over 600 mg/dl. So there may be some variances at the higher ranges, depending on the meter manufacturer, below 20 mg/dl is a standard definition of "LO" across the board of the human meters.
AlphaTrak Package Insert-Page 1
"The Alpha Trak meter displays results between 20 and 750 mg/dl. If the test result is lower than 20 mg/dl, "Low"/"LO" will appear on the meter display. If the test result is over 750 mg/dl, "High"/"HI" will appear on the meter display screen.
AlphaTrak has followed suit with the human standard of below 20 mg/dl corresponding as "LO".
GlucoVet and GlucoPet meters, however are not in keeping with the below 20 mg/dl "LO" standard:
"LO Reading: A Lo reading (under 10 mg/dL) is included in the memory."
"HI Reading: A HI reading (over 600 mg/dL) is included in the memory."

ReliOn (Wal-Mart/Sam's Club) has added a new, smaller meter to its diabetes products line. This is called the ReliOn Micro. It appears to be about the size of the LifeScan One Touch Ultra Mini, is a no strip coding required meter and takes only 0.3 microliters of blood for a test sample.
ReliOn Micro page
Price of the Micro is $12, with 50 test strips costing $21.94.
They still have the ReliOn Ultima which is $ 9, with 50 test strip costing $20, 100 cost $39; the Ultima takes 0. microliters of blood for a test.

This is probably more than you wanted to know about meters and altitude, but yes, it can affect them just as temperature extremes (hot or cold) can:
Effect of High Altitude on Blood Glucose Meter Performance
"Diabetes Technology & Therapeutics. December 2002, 4(5): 627-635
Participation in high-altitude wilderness activities may expose persons to extreme environmental conditions, and for those with diabetes mellitus, euglycemia is important to ensure safe travel. We conducted a field assessment of the precision and accuracy of seven commonly used blood glucose meters while mountaineering on Mount Rainier, located in Washington State (elevation 14,410 ft). At various elevations each climber-subject used the randomly assigned device to measure the glucose level of capillary blood and three different concentrations of standardized control solutions, and a venous sample was also collected for later glucose analysis. Ordinary least squares regression was used to assess the effect of elevation and of other environmental potential covariates on the precision and accuracy of blood glucose meters. Elevation affects glucometer precision (p = 0.08), but becomes less significant (p = 0.21) when adjusted for temperature and relative humidity. The overall effect of elevation was to underestimate glucose levels by approximately 1-2% (unadjusted) for each 1,000 ft gain in elevation. Blood glucose meter accuracy was affected by elevation (p = 0.03), temperature (p < 0.01), and relative humidity (p = 0.04) after adjustment for the other variables. The interaction between elevation and relative humidity had a meaningful but not statistically significant effect on accuracy (p = 0.07). Thus, elevation, temperature, and relative humidity affect blood glucose meter performance, and elevated glucose levels are more greatly underestimated at higher elevations. Further research will help to identify which blood glucose meters are best suited for specific environments."
Performance of Glucose Dehydrogenase–and Glucose Oxidase–Based Blood Glucose Meters at High Altitude and Low Temperature
"Blood glucose meters using the enzyme glucose oxidase (GO) have been proven unreliable at high altitude. A new test strip technology, based on the oxygen-insensitive enzyme glucose dehydrogenase (GD), has been utilized by some manufacturers.
"Five plasma-calibrated blood glucose meters were evaluated in this study, four glucose dehydrogenase based (GD1: Precision Xtra; GD2: Ascensia Contour; GD3: Accu-Chek Compact; and GD4: Freestyle) and one glucose oxidase based (GO1: OneTouch Ultra), with capillary blood samples from one of the investigators.
"First, all meters were tested in a hypobaric chamber at simulated altitudes (at 20°C in chronological order with ∼8-min intervals) of 0, 4,500, 2,500, and again 0 m above sea level, with normal (∼5.8-mmol/l) and high (∼16.5-mmol/l) plasma glucose values (n = 6 at all conditions). At 4,500 and 2,500 m altitude, the glucose oxidase-based meter (GO1) overestimated plasma glucose values by 15 ± 0.1% (mean ± SD) at the normal blood glucose level and 6.5 ± 0.5% at the high blood glucose level, as compared with the readings at 0 m.
"Comparatively, three glucose dehydrogenase–based meters overestimated readings of normal and high blood glucose levels (GD1 by 6.5 ± 0.2 and 1.5 ± 0.7%, GD3 by 3.7 ± 0.1 and 3.5 ± 0.4%, and GD4 by 0.8 ± 0.2 and 0.8 ± 0.4%, respectively). The fourth, GD2, underestimated readings of normal and high blood glucose levels by 1.9 ± 0.2 and 4.2 ± 0.9%, respectively.
"In addition, three glucose dehydrogenase–based meters (GD1, GD2, and GD3) were tested with blood at up to 5,895 m above sea level during the ascent of Mount Kilimanjaro, Tanzania. In the presence of both high altitude and low temperature, the meters diverged from each other. At the summit, 5,895 m above sea level, the readings of the investigator’s plasma glucose concentration were 2.8, 11.9, and 21.0 mmol/l (GD1, GD2, and GD3, respectively).
"In this study, all four glucose dehydrogenase–based meters performed better than the glucose oxidase–based meter at high altitude, as hypothesized.
"In conclusion, people with diabetes who intend to participate in activities at high altitude or, in particular, at low temperature, should be informed that blood glucose meters may give totally unreliable false low or high readings."
This deals with a change in the chemicals in the test strips which make it possible for the meter to read the blood drop. I believe most to all meters are now using the newer system, glucose dehydrogenase method.
"I lived in Leadville, Colorado (10,000 feet) and worked at the hospital there. We would frequently have companies come in to do tests on new glucose monitoring strips because they had to prove that the strips worked at altitiude. If we would let them poke our fingers several times we would receive a stipend in cash.
"When I moved to that elevation from about 4000 feet, I had to increase my basal insulin a couple of units."

This Diabetes Health Meter Review is 4 years old, but it gives you an idea of the altitude limit on some of the meters on page 2.
Adding here-altitude information on ReliOn Micro from the online owners' guide:
Altitude (up to) 10,000 feet

Some common blood glucose testing problems:
Common Problems with the Use of Glucose Meters
Useful Tips to Increase Accuracy and Reduce Errors in Test Results from Glucose Meters
Both links are useful to help you "troubleshoot" problems; interesting fact on both pages is that you can get a false low reading if the test strip is only partly inserted in the meter.
