Since not all vaccinated cats will be protected by vaccination, preventing exposure remains important even for vaccinated pets. FeLV vaccines will not cause false positive FeLV results on ELISA, IFA, or any other available FeLV tests.
How do snap test work?
The SNAP test is an enzyme immunoassay: after conjugate and test sample are mixed and added to the sample well, the device is then activated, releasing reagents stored within the device. Color development in the antigen indicator spots is proportional to the antigen concentration in the sample.
