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.
In the RFFIT, a total of 20 microscopic fields are read for each serum dilution, and compared against a control slide containing reference serum and virus dilutions. The number of infected fields for each serum dilution is used to determine the rabies virus neutralizing titer.Figure A: An example of a microscopic field where virus has been neutralized. Figure B: An example of a microscopic field where virus was not neutralized.he RFFIT is a rabies virus neutralization test performed in cell culture to determine the rabies virus neutralizing antibody level in human or animal sera. Immunofluorescent staining of infected cells is used as an indicator of rabies virus replication.
