Fluorescence Antibody Virus Neutralization Test


Category: Tag:


The result of the serological testing will be expressed in International Units per milliliter (IU/mL). Samples with a titer greater than the end point of the assay will be reported as ≥ the upper limit of the test. An antibody level ≥0.5 IU/ml is considered an adequate response to vaccination for the purposes of pet travel.

The FAVN test is only suitable to determine the antibody titer against rabies post vaccination, but not if there is a suspicion of clinical rabies in humans or animals.
