Different Species, Different Blood

Although the causes and effects of diabetes in pets are relatively similar to that in humans, it is important to note that the makeup of your pet’s blood is much different than your own.

The ratio of glucose in plasma and red blood cells differs among humans, cats and dogs. The amount of glucose in plasma is 87.5% for dogs and 93% for cats. Humans have a significantly lower amount of glucose in the blood, with just 58%.

This difference means that detecting and managing diabetes in pets takes specific tools and techniques.

Differences in the Distribution of Glucose in Whole Blood


Sometimes, pet owners choose to use human blood glucose monitors, which are created and calibrated for measuring the level of glucose in a human’s blood. When a human blood glucose meter is used on a dog or cat, it assumes human blood composition to calculate glucose levels. This results in underestimation of blood glucose concentrations and inaccurate readings.

To get accurate blood glucose readings on your diabetic dog or cat, you must use a blood glucose monitor made specifically for dogs and cats. AlphaTRAK Blood Glucose Monitoring System is calibrated specifically for dogs and cats. Learn more about AlphaTRAK for the management of your pet’s diabetes.
