Rabies Antibody Test for Pet Travel (FAVN)
The Rabies Antibody Titre – Fluorescent Antibody Virus Neutralization (FAVN) Test measures the level of rabies antibodies in an animal’s blood to evaluate the immune response following rabies vaccination. This virus neutralization assay is designed to determine if an animal has developed an adequate level of immunity to rabies as per international standards. The FAVN test is particularly required for animals traveling to rabies-free countries or regions to confirm vaccination compliance. This highly specific test detects neutralizing antibodies against the rabies virus, ensuring accurate assessment of the vaccine-induced immune response and aiding in compliance with regulatory health requirements for travel.
4 ml Serum
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.
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.
