Did you know that a single blood test can reveal if your cat or dog is truly protected against deadly diseases like rabies, distemper, or parvovirus? That’s the power of the titer test. As more pet owners seek alternatives to routine vaccinations, understanding titer testing has never been more important. Whether you are planning international travel, have a pet with health concerns, or simply want to avoid over-vaccination, this guide will walk you through everything you need to know about titer tests for cats and dogs. Let’s dive in!

What is a Titer Test?

This is a blood test that will measure the number of antibodies there are to specific diseases. For example, parvovirus, canine distemper, etc.

The goal for this test is to determine your kiddo has sufficient immunity from specific diseases.

The most commonly tested diseases are Rabies, feline and canine distemper, canine parvovirus, canine adenovirus, feline panleukopenia, feline herpesvirus, feline calicivirus.

Results are indicated by high/ positive indicating that your kiddo is protected. Low/ negative may suggest the kiddo has low protection.

This is a great option for immuno-compromised kiddos, dogs who have bad reactions to vaccines, and for owners who are worried about over vaccinating their kiddo. The best way to inquire about the titer test is doing your research and talk with your veterinarian about it and why you would like the titer test. I will go over more details and process in a different article.

Titer test labs are typically sent out to a third party (because the in- house option is not as popular amongst practices) and results can be received same day or following day (only for specific companies and tests). For bigger tests like FAVN will take 1-4 weeks for results to get back in.

How is the Titer Test Performed?

The Titer Test is a blood test. They need between 1-3 milliliters of blood depending on if a single or all diseases will be tested. There is not swab test for a Titer Test.

For a dog: Blood is typically drawn from a front leg or jugular vein.

For a cat: Blood is typically drawn from the jugular vein, a front leg, or a back inner thigh (last resort).

I will be honest; these are not comfortable for fun for the kiddos. They are not happy to be held in place and especially poked with a needle. The vet staff will do their best to help your kiddo be as comfortable as they possibly can and provide treats if your kiddo will accept it. Your kiddo does have to be held in a certain position to protect.

Veterinary practices have started getting certified in the Fear Free Method. This is where the staff is trained to be the least restrictive possible with getting the job done and helping comfort your kiddo during the process. When you are looking for a vet practice, look for Fear Free Certified if you prefer this option.

Types of Titer Test Available

There are in house kits that some (not all) practices have available. This option tends to not be as popular as I can be less accurate than sending the blood to a 3rd party lab.

The 3rd party lab will be the most thorough option, but also the longest wait and most expensive.

What Countries Have the Titer Test?

Most countries have access to a Titer Test for pets due to the test being required for your pet to travel to Rabies-free countries or regions (example: Japan, Australia, New Zealand, Hawaii).

Titer test is most commonly used for Rabies because there are some kiddos who travel a lot with their owners or are immuno-compromised. Most countries will accept a Titer Test over a Rabies vaccine for your kiddo, but some do not.

It is best to check with the local authorities and laws or vet for country-specific regulations.

When to Consider a Titer Test

Before Vaccination: To avoid unnecessary vaccines if your pet is already protected. Be sure to check your country and region laws.
International Travel: Many countries require proof of rabies immunity via Titer Test
Pets with Health Issues: This can be kiddos with allergies to vaccines or immune disorders.
Senior Pets: Assess immunity without over-vaccinating our older animals.
Holistic or minimal vaccination protocols (check your country and regional laws).
Breeding: Ensuring immunity before pregnancy.
