Rabies Antibody Titre Test: What It Shows and What It Does Not

A rabies antibody titre test measures the antibodies in a dog's or cat's blood to show whether a vaccinated pet has responded to the rabies vaccine. It does not show whether a pet has rabies, and it does not replace the vaccination record. Anyone bitten or scratched by any animal must see a doctor at once.

What is an antibody titre?

After a vaccine, a healthy pet's body makes antibodies. These are small proteins from the immune system that can recognise a particular germ. A titre is simply a way of saying how much of one antibody the blood holds. It is not the same in every pet, because age, general health and the time since vaccination can all play a part.

The Rabies Antibody Titre (ELISA) uses serum, which is the clear part of the blood left after the cells are separated. ELISA is a lab method in which antibodies in the serum cause a colour change on a special plate. A vet or the lab collects the blood, and the lab confirms the method, sample needs and reporting time when you book.

What does the result tell you?

It tells your vet that the pet's blood holds rabies antibodies, which suggests the body responded to the vaccine. The report lists the result and the lab's reference information. A registered veterinarian reads it with your pet's vaccination record, age and general health.

This guide gives no numbers on purpose. What counts as an acceptable result is decided by whoever asks for the test, such as a destination country, and not by this website.

Think of the report as one page in a file. The vaccination certificate is another page, and the vet's examination is a third. A titre read on its own, away from that file, can mislead.

What does it not tell you?

• It does not show infection. No result, high or low, tells you whether a pet has the disease.
• It is not a safety certificate. A good result does not make a bite or scratch harmless, and it does not replace the vaccination certificate.
• A low result does not mean rabies. In a vaccinated pet it may reflect a weak response or a poorly timed sample. Your vet decides what to do next, including whether to talk about vaccination again.
• It cannot guide first aid. If a person has been bitten or scratched, nobody should wait for a pet's blood report.

Why would an owner need one?

The usual reason is travel. Some destinations want evidence that a vaccinated pet has made antibodies before it is allowed in. Rules differ from place to place, and some accept only certain methods or approved laboratories, so check with the destination first. The lab cannot promise that any country will accept its report.

Whatever the reason, carry your pet's vaccination certificate to the visit. The result only makes sense when it is read next to that record, and a vet or an official may ask to see both together.

Which other checks go with it?

Owners preparing for a journey often add a Complete Blood Count (CBC), which counts the blood cells and gives a general view of health. The Pet Travel Check with Rabies Titre groups the titre with blood, parasite, liver and kidney checks for dogs and cats that will travel. Your vet can add or drop items to suit your pet.

What about bites and scratches?

Rabies is a fatal disease that can pass from animals to people, usually through a bite or scratch. Anyone bitten or scratched by a dog, a cat or any other animal must see a doctor at once. Tell the doctor exactly what happened, and tell your vet too.

Do not rely on a titre result, a vaccination history or the animal's appearance to decide that a wound is harmless. A pet that suddenly behaves oddly should be seen by a vet urgently, and kept away from children while you arrange it.
