PetTest Advocate Blood Glucose Test Strips are designed to be used with either the Advocate PetTest Glucose Meter System (not included). They are designed to help quantitatively measure your pet’s glucose levels from blood samples taken from your feline friend or canine companion. And since each test only requires a small blood sample of 0.3 microliters, using these strips can help reduce the stress of testing for you and your paw-tner, while still providing accurate results.
