Feline Vaccine Screen
The Feline Vaccine Screen is a diagnostic panel designed to evaluate antibody levels in cats against three key feline pathogens: Feline Herpesvirus (FHV), Feline Calicivirus (FCV), and Feline Panleukopenia Virus (FPV). The panel uses virus neutralization (VN) tests for FHV and FCV and a hemagglutination inhibition (HI) test for FPV. By measuring antibody titers, this screen helps to assess a cat’s immunity status, particularly after vaccination or prior exposure to these viruses. High antibody levels indicate adequate immunity, reducing the need for booster vaccines, while low titers may suggest the need for revaccination. This test is especially valuable for managing vaccination schedules in multi-cat environments, shelters, or high-risk settings.

Specimen
2 ml Serum
Collection Guidelines
- Collect an adequate amount of blood in a plain red-top tube or serum separator tube (yellow-top tube). Allow it to clot at room temperature for 30 to 60 minutes before separation.
- Centrifuge to separate the serum. Transfer the clear serum into a new, leak-proof plain red-top tube and label it as “serum.”
- Excessively hemolyzed samples are not suitable for this test.
- Unspun samples will not be accepted.
- Refrigerate sample at 4oC until shipment.
Turnaround time
14-21 days
Packing Instructions
Label each sample with the animal’s name and a unique identifier, using a permanent marker or a secure adhesive label. Ensure the submittal form is completed with the animal’s information and relevant medical history.
