Feline Leukemia Virus FeLV Ag Rapid Test Kit

Product Code
Kit Principle



Feline leukemia Virus FeLV Ag Rapid Test Kit is based on an immunochromatographic assay to detect FeLV Ag in feline serum or blood. Result in 10-15min, which is rapid, accurate and easy-to-operate.

Feline leukemia virus is a retrovirus that infects cats. FeLV can be transmitted from infected cats when the transfer of saliva or nasal secretions is involved. Cats persistently infected with FeLV serve as sources of infection for other cats. The virus is shed in saliva, nasal secretions, urine, feces, and milk of infected cats.

What causes FeLV infection?

FeLV is categorized into four subgroups, A, B, C and T. An infected cat has a combination of FeLV-A and one or more of the other subgroups. Exposure to the feline leukemia virus doesn’t have to be a death sentence; about 70% of cats who encounter the virus are able to resist infection or eliminate the virus on their own.

Why and how might my cat become infected?

Feline leukemia is a disease that only affects cats -- it cannot be transmitted to people, dogs, or other animals. FeLV is passed from one cat to another through saliva, blood, and to some extent, urine and feces. The virus does not live long outside the cat’s body -- probably just a few hours. Grooming and fighting seem to be the commonest ways for infection to spread. Kittens can contract the disease in utero or through an infected mother’s milk. The disease is often spread by apparently healthy cats, so even if a cat appears healthy, it may be infected and able to transmit the virus.

What happens during infection and how to diagnose it?

After being exposed to FeLV, the incubation period is two to 14 days before symptoms appear. 

Commercial labs detect the presence of FeLV in two ways: by ELISA antigen testing or through reverse transcriptase PCR (RT-PCR), a procedure that detects a segment of genetic material that is specific to leukemia virus. Both tests are equally effective, though the RT-PCR test may be more common in some areas.

Test results should be interpreted carefully. Please always follow the advice of the doctor.
