Human vs. Pet Glucose Meters
Why Human Glucose Meters Put Diabetic Pets at Risk
Using a human meter on your dog or cat can lead to dangerously inaccurate readings. Here is the science behind the "false low" and how to properly monitor your pet between vet visits.
The Science of the "False Low"
Same drop of blood. Two very different stories.
Human blood glucose meters are calibrated specifically for human blood chemistry. When you place a drop of pet blood on a human test strip, the meter’s algorithm gets confused.
Because pets carry significantly less glucose in their red blood cells compared to humans, a human meter will consistently underestimate a pet's actual blood sugar level. You might see a "safe" number on the screen, when in reality, your pet is experiencing dangerous hyperglycaemia.

Why Testing at Home is Crucial
The BSAVA (British Small Animal Veterinary Association) suggests regularly checking blood glucose, ketones, and urine glucose levels. While the historic median lifespan of a diabetic dog was 2.5 years, careful home monitoring can extend their lifespan significantly by maintaining good blood glucose control.
1. Track Daily Fluctuations
A single test at the veterinary practice only shows a snapshot. Daily home testing clearly shows how specific foods and insulin doses affect your pet in real-time.
2. Catch Emergencies Early
Testing alerts you immediately when something isn’t right, allowing you to treat hypoglycaemia (low blood sugar) or hyperglycaemia (high blood sugar) before it becomes fatal.
3. Monitor for Ketones
When the body doesn't have enough insulin, it breaks down fat for fuel, producing ketones. Catching this early prevents Diabetic Ketoacidosis (DKA), a severe and costly complication.
The PetTest Home Monitoring Range
PetTest meters are engineered with species-specific algorithms. With the flip of a switch, the meter recalibrates for either dog or cat blood chemistry, ensuring vet-accurate results.
