My Pet Tested Positive for Lyme Disease—Now What?

When your pet tests positive for Lyme disease, we follow up with a specialized blood test called the C6 antibody test, offered through IDEXX Laboratories. This test measures the level of antibodies against the Lyme-causing bacterium, Borrelia burgdorferi. A high C6 value typically indicates an active infection, and in these cases, we recommend starting treatment right away.
