Feline immunodeficiency virus (FIV) is a lentivirus that affects cats worldwide with 2.5% to 4.4% of felines being infected.FIV affects 23% of cats in the US and testing is readily available.
The FelineVMA recommends testing cats and kittens at the time they are acquired, prior to initial vaccination for FeLV (or FIV in regions the vaccine is available), following potential exposure to infected cats or cats of unknown status, and when presenting for illness, even if they have previously tested negative.
Moving forward, it's essential to keep these visual contexts in mind when discussing Fiv Testing And Diagnosis For Cat Breeders.
Important note about FIV vaccines Cats vaccinated with whole-virus FIV vaccines will test positive on FIV antibody diagnostics, including the SNAP Feline Triple Test, SNAP FIV/FeLV Combo Test, PetChek FIV Antibody Test, and Western blot. Therefore, if choosing to vaccinate, test immediately prior to administration.

Kittens Kittens born to an FIV-positive mother can have maternal FIV antibodies until they are five to six months old, meaning if they were tested younger than six months of age using a screening test, it is likely that they would show positive results. Because the PCR test looks for actual genetic material, it is very useful in the diagnosis of infection in young kittens which may have ...
A positive POC for FIV test indicates the presence of FIV antibodies. Infected cats will be positive for FIV antibodies 60+ days post-infection. If the patient test is negative, the patient should be retested for FIV in 60 days. Confirmatory testing is ideal and may include a different manufacturers POC test, a PCR test, or a Western Blot test.
Antibody tests are most commonly used for FIV diagnosis. All FIV tests that detect antibody (a, b) can be influenced by the presence of maternally derived antibodies (MDA). Kittens born to an FIV-infected queen become infected only rarely, but they will test positive for FIV antibodies because of the MDA that are present in their blood.
Since FIV vaccination only has a reported field effectiveness of 56% in Australia, and possibly lower in NZ, FIV-vaccinated cats should undergo annual FIV testing prior to annual FIV re-vaccination using a suitable PoC kit to check infection has not occurred in the preceding year.
