Diagnostic test for Feline Leukemia Virus FeLV Ag

Feline leukemia is an infectious disease caused by the Retrovirus. The sick animal or asymptomatic carrier expels the virus with saliva, feces, urine, milk and other secretions. It is assumed that infection occurs because of a long-term contact with the virus carrier.
The disease is chronic, the symptoms vary. It often leads to emaciation, apathy, anemia, dehydration and loss of appetite. Some cats suffer soon after infection. In the majority of cases, the disease develops for years, and some are able to fight the virus.
If the rapid immunochromatographic test is positive, confirm the test by other methods in the laboratory.
A negative result also does not exclude leukemia in 100%. If the symptoms may indicate FeLV - the test should be repeated or confirmed in the laboratory by other methods.
