FIV/FeLV – Combined Rapid Test for Feline Immunodeficiency Virus and Feline Leukaemia
This 10-pack contains 10 rapid tests (2 × 5-pack) at a lower price per test – handy for multi-pet homes, breeders and shelters.
Feline immunodeficiency virus (FIV, “feline AIDS”) and feline leukaemia virus (FeLV) are the two most important chronic viral infections in cats. Both can stay symptom-free for years while gradually wearing down the immune system. This combined test checks for both from a single blood sample.
Accuracy – manufacturer validation
The manufacturer validated the two parameters separately:

When is the test recommended?
- Before adopting or taking in a new cat — the most important occasion
- For outdoor cats that have been in fights (FIV is mainly spread through bites)
- Recurring infections that are slow to heal: mouth inflammation, abscesses, upper respiratory problems
- Unexplained weight loss, persistent fever, enlarged lymph nodes
- In multi-cat households, before introducing a new animal
- For breeders, as regular screening of breeding cats
How does it work? Three steps
- 1
Take a fresh blood sample with the pipette provided. Serum and plasma can also be used. It is best to have the blood sample taken by a vet.
- 2
Put the sample into the sample well of the cassette, then add the buffer as described in the manufacturer's instructions.
- 3
Read the result after the time stated in the instructions. The cassette has two separate test lines: one for FIV and one for FeLV.
Reading the result

Positive
The test line that appears shows which pathogen is positive — it can be one of them or both. Even a faint line is positive. See your vet for a confirmatory test.

Negative
Neither pathogen detected. After a recent infection it can take weeks for FIV antibodies to appear, so after a known exposure it is worth repeating the test 60 days later.

Invalid
No control line, so the result cannot be interpreted. Repeat the test with a new cassette.
Good to know
- A cat vaccinated against FIV can be antibody-positive without being infected. If your cat has been vaccinated, tell your vet.
- In kittens up to 6 months of age, maternal antibodies can make the FIV result misleading — repeat testing is needed.
- Some FeLV infections are transient: in many cases the cat overcomes the virus, so a positive result should always be re-checked a few months later.
- A negative cat can live alongside a positive one — but discuss the living arrangements with your vet.
