Our greatest concern is the well-being of your pet. Before putting your pet under anesthesia, we highly recommend, and actually require for older pets, that a Pre-Anesthetic Blood Profile be performed on all pets undergoing anesthesia to maximize patient safety. Our greatest concern is the well-being of your pet. Before putting your pet under anesthesia, we highly recommend and actually require for pets over the age of 6, that a Pre-Anesthetic Blood Profile be performed on all pets undergoing anesthesia to maximize patient safety. The Pre-Anesthetic Blood Profile helps alert our doctor to the presence of dehydration, anemia, infection, kidney disease, liver disease, or any other issues that could complicate the procedure. The tests are similar to what your own physician would run if you were to go under anesthesia. In addition, these tests may be useful if your pet’s health changes to develop faster and more accurate diagnoses and treatments.
