Zoetis Launches New WITNESS® FeLV-FIV Combination Test
First FeLV-FIV point-of-care test that is stable at room temperature and does not require snapping
FLORHAM PARK, N.J., Dec.15, 2014 — Zoetis today announced that the new combination WITNESS® FeLV-FIV Feline Leukemia Virus (FeLV) Antigen and Feline Immunodeficiency Virus (FIV) Antibody Test Kit is now available for preorder by veterinary practices nationwide. The new test offers veterinarians an accurate and cost-effective point-of-care option that requires no refrigeration or snapping.
The WITNESS FeLV-FIV Test Kit uses Rapid Immuno Migration (RIM™) technology to detect the presence of FeLV antigen and FIV antibodies, providing results in approximately 10 minutes. Shipments of the new test will begin on January 5, 2015.
“The new WITNESS FeLV-FIV Test Kit provides veterinary practices another dependable and affordable tool to support them in detecting leukemia virus antigen and immunodeficiency virus antibodies in their feline patients,” said J. Michael McFarland, DVM, DABVP and group director of Companion Animal Veterinary Operations for Zoetis. “Since the WITNESS FeLV-FIV Test Kit does not require refrigeration, it is easy to store, does not take up refrigerator space, and veterinarians don’t need to wait for it to come to room temperature to use.”
Excellent Sensitivity* and Specificity**
In a series of clinical tests conducted by Zoetis, the WITNESS FeLV-FIV Test demonstrated excellent sensitivity and specificity†:
- 92.9 percent sensitivity and 96.5 percent specificity for FeLV1
- 93.8 percent sensitivity and 93.4 percent specificity for FIV 2
AAFP Recommends Testing
According to its 2008 Feline Retrovirus Management Guidelines,3 the American Association of Feline Practitioners (AAFP) suggests that cats may require retrovirus testing at different times in their lives and all cats should be tested before initial vaccination against FeLV or FIV.
Among the candidates AAFP suggests for FeLV and FIV testing are:
- Cats and kittens when they are first acquired and before initial vaccination
- Sick cats, even if they have tested negative in the past
- Cats with known recent exposure to a retrovirus-infected cat or to a cat with unknown status, particularly via a bite wound, regardless of previous test results
- Cats living in households with other cats infected with FeLV or FIV, on an annual basis unless they are isolated
- Cats with high-risk lifestyles (e.g., cats that have access to the outdoors in cat-dense neighborhoods)
About Feline Leukemia Virus and Feline Immunodeficiency Virus
The retroviruses FeLV and FIV are two common pathogens of cats that can cause severe, sometimes fatal diseases. According to the Cornell University College of Veterinary Medicine, in the U.S., approximately 2 to 4 percent of all cats are infected with FeLV. Rates rise significantly—13 percent or more—in cats that are ill, very young or otherwise at high risk of infection. Additionally, kittens are much more susceptible to infection than adult cats, and therefore are at the greatest risk of infection if exposed.4
Cornell cites that in the U.S., approximately 1.5 to 3 percent of healthy cats are infected with FIV. Rates rise significantly—15 percent or more—in cats that are sick or at high risk of infection.5

The WITNESSFeLV-FIV Test Kit is indicated for use when history and/or clinical signs may suggest an infection by feline retroviruses in at-risk populations. The new test kit joins the WITNESS line of point-of-care diagnostic tests offered by Zoetis.
