AlphaTRAK 2 is the blood glucose monitor used and prescribed the most among vets1. AlphaTRAK is calibrated for dogs and cats and accounts for the differences in the blood composition of different species. Results are accurate, easy to obtain from the comfort of home and available quickly. Sometimes pet parents choose to use human blood glucose meters instead of a pet glucometer. Human meters are created and calibrated for measuring the concentration of glucose in a human’s blood. When a human blood glucose meter is used for a dog or cat, it assumes human blood composition to calculate glucose levels. This can result in underestimation of blood glucose concentrations and inaccurate readings.
