Rabies Antibody Endpoint
Reference Values Describes reference intervals and additional information for interpretation of test results. May include intervals based on age and sex when appropriate. Intervals are Mayo-derived, unless otherwise designated. If an interpretive report is provided, the reference value field will state this.
Reportable range is 0.1 to 15.0 IU/mL
Less than 0.1 IU/mL: Below detection limit
>15.0 IU/mL or >14.0 IU/mL: Above reportable range
In humans a result of 0.5 IU/mL or higher is considered acceptable according to the World Health Organization (WHO) guidelines; see WHO and Advisory Committee on Immunization Practices documents for additional guidance.

Qualitative results. For those who want to know if they need a booster of rabies vaccine.
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. The antibodies are called rabies virus neutralizing antibodies (RVNA).
