PetTest Advocate Lancing Device provides an easy-to-use method to track your pet's blood sugar levels in the comfort of your own home. This device is designed to work with PetTest Twist Top Lancets, along with most brands of universal lancets. The six depth settings help you achieve samples from any skin type, while the precise linear sliding motion helps reduce pain—no more worrying about the discomfort that comes from the side-to-side motion other lancets can produce. Not only does this device feature a 2-hand lancet disposal system, so you can safely remove used lancets, but it also helps make testing less stressful for you and your pet.
