Interacting with ADW customers is one of the best parts of my job. As the staff veterinarian at ADW, I get great access to lots of diabetic pet owners and then I can translate our talks into newsletters that may be of value to all of you.
Here is a small sampling of the email encounters I’ve had in just the last few days. Maybe you, too, will pick up something new.
What does it mean when a glucose meter reads “hi” or “lo”?
When a glucose meter gives the reading “hi” or “high” it means that the glucose level is above whatever maximum level the meter can read. In the past, most meters topped out at about 500 mg/dl. The AlphaTRAK 2 meter can read up to levels of 750 mg/dl. Honestly, any number over 500 is not good!
If a meter reads “lo” it probably is below 20 mg/dl. You need to read the fine print of whichever meter you use, but for most meters “lo” is 20 or less. This, too, is a crummy and dangerous number to have!
Does the number on the test strip bottle have anything to do with the glucose level?
I hadn’t ever thought too closely as to why various batches (both human and pet calibrated meters) are coded differently. This client had a good question! For decades I had simply accepted that we just do it – change the code for a new bottle or change the code to match the number for the species on the bottle. The coding has to do with the calibration for that batch of test strips. It is certainly a potential source of error if the user doesn’t change the code when a new batch of test strips is opened. Some human glucose meters are getting away from changing the code bottle to bottle and I imagine that, in time pet glucose meters will follow suit.
Nonetheless, for the pet glucose meters you need to code for the species (ie the AlphaTRAK meter) or use a different chip (ie the IPet meter) for dogs versus cats. The number coded on the bottle has nothing to do with the glucose level of the pet. Pay attention – if you don’t code correctly you can get erroneous blood glucose results.
Do I really need to shell out the money for a pet calibrated glucose meter when I was given a human glucose meter for free from a friend?
Human glucose meters tend to underestimate the glucose level of a dog or cat. It has to do with how much of the glucose is in the plasma versus the red blood cells between species. This varies between dogs versus humans versus cats.
For many years we didn’t have glucose meters calibrated for dogs and cats. Veterinarians used human meters for pets. Some were better than others. Some required more blood than others. Now that we have pet glucose meters I strongly encourage owners to use them. Yes, it’s a smaller market than the vast human diabetes market which means the test strips may cost a bit more. Nonetheless, the improved accuracy can make a world of difference in you diabetic pet’s health. The better the glucose regulation the less likely it is for a pet to wind up in the ER in a crisis. Diabetic complications and visits to the ER can set you back a lot more money than a bit extra in test strips for a pet glucose meter compared to a human glucose meter.
I’m always happy to have ADWDiabetes readers send me questions.It is where many of these newsletter ideas come from! Keep those questions coming to firstname.lastname@example.org.
NOTE: Consult your veterinarian to confirm that my recommendations are applicable for the health needs of your pet.
