National Veterinary Laboratory

National Veterinary Laboratory is the oldest private veterinary diagnostic laboratory in the United States, located in Franklin Lakes, NJ. We specialize in tests for feline diseases.

We provide critical diagnostic services including tests for Feline Leukemia Virus (FeLV), Bartonella (Cat Scratch Disease Bacteria), and Feline Immunodeficiency Virus (FIV).

In 1974, we developed the first FeLV test, the FeLeuk® IFA Test, considered the Gold Standard. We have since performed over 1,300,000 FeLeuk® Tests.

For 50 years, National Veterinary Laboratory has been dedicated to providing accurate results for feline diagnostics and helping veterinarians control and prevent the spread of feline pathogens.
