FeLV/FIV Blood Test
The FeLV/FIV test is a simple blood test that detects the presence of either Feline Leukemia Virus or Feline Immunodeficiency Virus in cats.
A false positive result is possible in a small percentage of cats. So if your cat shows positive for either disease, a second test administered 30-60 days later is recommended.
This test can be a good way to screen your cat for more than one life-threatening disease at one time.
Vaccination is not that effective – not recommended. There are different strains of virus and we are not always sure which is present in the population. The vaccine doesn’t contain all strains.
