Rapid Fluorescent Focus Inhibition Test (RFFIT)

0.1 to 15.0IU/mL

Results are reported as either <0.1 IU/mL, ≥ 0.1 IU/mL or ≥ 0.5 IU/mL.

RFFIT stands for Rapid Fluorescent Foci Inhibition Test. It is a serum neutralization (inhibition) test, which means it measures the ability of rabies specific antibodies to neutralize rabies virus and prevent the virus from infecting cells. These antibodies are called rabies virus neutralizing antibodies (RVNA).
