Which vaccinations can a titer test check, and how does it work?

A titer test measures the level of antibodies in your dog’s blood to determine whether vaccination is currently needed. This helps avoid unnecessary vaccinations.

For dogs, a titer test can be done for distemper, hepatitis, and parvovirus. The test requires only a small blood sample, and results are usually available quickly. Based on the results, the veterinarian can decide whether your dog needs a vaccination or is still adequately protected.
