FASTest FeLV Single Test

Qualitative Detection Of Feline Leukaemia Virus

Test applicable to: Cat
Sample: Whole Blood, Serum and Plasma

FASTest FeLV is based on a rapid immunochromatographic technique. Extracellular FeLV-Antigens in the sample will form specific antigen-antibody complexes in the sample area. Lateral flow (migration) towards the FeLV areas (marked ‘T’ on the slide) allows these complexes to bind with gold particles labelled with monoclonal FeLV antibodies to form a pink-purple Test line. A correct test procedure will be indicated by a second pink-purple line in the Control area (marked ‘C’ on the slide).

Why is it important to test for FeLV?

Feline Leukaemia Virus (FeLV) is found worldwide in cats. Depending on their age, health, environment, and lifestyle the prevalence of infection can vary greatly. FeLV-Antigen detection is accepted as the method of first choice for the diagnosis of infection. FeLV infected viraemic cats normally show high concentrations of extracellular (free) FeLV-Antigen in their blood 3 weeks post-infection. Based on highly specific monoclonal FeLV-Antibodies FASTest FeLV is an important diagnostic tool for the detection of infected cats.

What are the symptoms of FeLV?

Clinical signs are progressive deterioration of the cat’s health which can be interspersed with periods of relatively good health. In the early stages of the FeLV infection, it is not unusual for cats to show no signs of the disease at all. Some signs may appear after months or even years after the infection.
