The Rabies Titer Test or RFFIT is used to monitor rabies antibody levels in someone who may have an occupational risk of rabies, such as veterinarians or rabies lab workers, or someone who has been exposed to rabies and needs to be monitored to ensure that the vaccination is effective.
A titer (or titre) is a way of expressing concentration. Titer testing employs serial dilution to obtain approximate quantitative information from an analytical procedure that inherently only evaluates as positive or negative. The titer corresponds to the highest dilution factor that still yields a positive reading. For example, positive readings in the first 8 serial twofold dilutions translate into a titer of 1:256 (i.e., 2 â8). Titers are sometimes expressed by the denominator only, for example 1:256 is written 256.
