Advanced diagnostic tests help us better understand the specific type and behavior of your pet’s cancer. Techniques like flow cytometry, immunohistochemistry (IHC), molecular testing, and PARR (PCR for Antigen Receptor Rearrangement) provide critical information that cannot be seen under a microscope alone. These tools help determine how aggressive the cancer is, where it originated, and how it may respond to different treatments.

By using these tests, we can classify cancers more precisely and develop a treatment plan that fits your pet’s condition. Samples for these tests typically come from biopsies, aspirates, or fluid collections, and are evaluated by specialized veterinary laboratories. While not needed in every case, advanced diagnostics are especially helpful for cancers like lymphoma, undifferentiated tumors, or when a diagnosis is uncertain. They allow us to move forward with confidence, knowing we’ve made the most informed decision possible.
