A panel of 8 samples, including six RNA extracts from different rabies isolates and two NTC's (no tissue control). The source of the rabies isolates can be modified to meet individual needs, area/region isolated from, host species, etc. Also, the panel can be anonymised so that the receiving laboratory does not know which samples are positive and negative, the results will be given on request from the lab. The panel would be ideal for testing staff competence and proficiency.
