An in vitro c-ELISA method was tested in view of replacing the in vivo MNT assay.
This ELISA is able to detect equine immunoglobulin against rabies with neutralising activity.
As the MNT test this c-ELISA is able to discriminate non-compliant vaccine batches.
The c-ELISA is a potential tool for detection of human immunoglobulin against rabies.
