Titres are also used to check the concentration of viruses or bacteria in the blood. The titer of an antibody is associated with the number of times one can dilute a sample of blood and still detect the antibody.

One more use for a titre test is to ascertain the presence of a disease by examining the concentration of viruses or bacteria in the blood or by examining the antibodies. 2  Various diseases in which this can be helpful include mononucleosis, Lyme disease, or hepatitis.
