The combined feline leukemia virus (FeLV) and feline immunodeficiency virus (FIV) antibody test, often administered via a rapid immunochromatographic assay (sometimes referred to as a “SNAP” test), detects the presence or absence of antibodies produced by a cat’s immune system in response to these viruses. A positive result indicates exposure and potential infection, while a negative result suggests the absence of antibodies. For example, a single line appearing on the test strip at the control position indicates a negative result, while two lines (one at the control and one at the test position) signify a positive result. It’s important to note that these tests detect antibodies, not the viruses themselves.
Early and accurate diagnosis of these retroviral infections is critical for managing feline health. These tests offer rapid, point-of-care results that can inform treatment decisions and prevent transmission to other cats. Understanding a cat’s FeLV/FIV status helps veterinarians recommend appropriate vaccination strategies, isolate infected animals to minimize spread, and provide tailored supportive care. This accessible diagnostic tool has revolutionized the approach to feline retroviral diseases, enabling proactive intervention and improved outcomes.
