A titer test (spelt “titre” in the UK) is a diagnostic lab test. It measures the level of antibodies circulating in the blood. These antibodies are produced when antigens (like a virus or bacteria) produce a response from the immune system.

It’s a simple procedure where a small sample of blood is drawn from the animal. The sample is diluted, and the antibodies are measured. The titer level is expressed as a ratio – revealing how many times the blood can be diluted before no antibodies are detected.
