From Victoria, Australia:
As a keen bushwalker, cross-country/downhill skier, rock climber and caver, a lot of my time is spent outdoors. Unfortunately, my blood glucose monitoring equipment (an outdated 8-year old Reflolux II (from Boehringer Mannheim) does not give valid results (or any result) for temperatures below about 20 degrees (Celcius).
Is there any meter that can provide good results down to about 0 degrees Celcius (32 degrees Fahrenheit)?
Is it permissible to warm the test strips/meter beforehand (e.g., tuck in jumper) to get them to 20 degrees or so before taking the reading?
Regards from sunny Australia!
Probably some of the newer meters would be of benefit to you. The Accuchek Advantage by Boehringer Mannheim (probably sold under another name outside the U.S., such as Accutrend), or the One-Touch Profile by LifeScan, should work at these temperatures. You should check with the manufacturers of the various meters about their recommendations.
The meter probably yes, the strips probably not. Why not keep them in your jumper to keep them warm all the time they're not in use?
Additional Comment by Dr. O'BrienThe two meters recommended for outdoors types, i.e. hikers, climbers skiers, in this part of the world [Colorado, USA] are the
- Glucometer Elite, (10 degrees C to 40 degrees C) which is a glucose oxidase system, and the
- Glucometer Encore, (17 degrees C to 30 degrees C) which is non-enzymatic.
In order to get around the problem of keeping the meter at a reasonable temperature, you might try using strips that are meant to be read visually. These could be kept warm in clothing and since it is presumably hypoglycemia from excercise that you want to guard against primarily, they might work fine. Remember though, that the tendency with these strips is to read too low and that this is especially so if a person is dehydrated.
