Reference Values
Reportable range is 0.1 IU/mL to 15.0 IU/mL
Less than 0.1 IU/mL: Below detection limit
In humans a result of 0.5 IU/mL or higher is considered an acceptable response to rabies vaccination according to the World Health Organization (WHO) guidelines; see WHO and Advisory Committee on Immunization Practices documents for additional guidance.
Interpretation
Quantitative results. For those who want to know their exact titer between the reportable range.
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).
