Speed FeLV
Why use Speed FeLV ?
Feline leukemogenesis virus (FeLV) infection produces highly variable and unspecific symptoms that may be common to other viral or immune-mediated diseases. In Europe, only 20-30% of cats are vaccinated against FeLV, and the disease affects around 2-3% of cats (2).
Diagnosis of FeLV is sometimes complicated by the specificity of RNA retroviruses which, after a blood and saliva viremia phase, integrate into the DNA of their host. Depending on the animal's immune response and viral load, the viral infection can evolve in several ways: abortive,regressive (latent) or progressive (active). FeLV is a serious, contagious disease that causes lymphoid tumors and is associated with a high mortality rate.
Regular screening of exposed cats, particularly before vaccination, is considered the best way to combat the virus (2).
Testing for soluble viral antigens enables us to determine the animal's status, even when the viral load in the blood is low (early infection, transient viremia, sequestered infection).
When to use Speed FeLV ?
Speed FeLV is a tool for regular monitoring of FeLV status:
It can be used at every annual visit or before sterilization, and more frequently when a cat is regularly exposed to the virus.
Knowing the status of new cats before introduction in a muti-cat environment to help prevent exposure of healthy cats.
Following potential exposure to the virus, the animal's status can be tested 28 to 30 days later.
Speed FeLV is recommended prior to FeLV vaccination, to prevent vaccine failure.
In cats with compatible symptoms
Quick guide
1. Add 1 drop of sample into the sample well.
