Rapid Testing Using Vidas

ALcontrol Laboratories have been granted UKAS accreditation for new Salmonella and Listeria methods using the VIDAS technology.

VIDAS provides all the speed and advantages of our routine ELISA methods but unlike ELISA methods this rapid procedure has been approved by M&S so offers an alternative to the slower, cultural methods. VIDAS will provide a negative result at least 24 hours earlier than the cultural methods specified by M&S.

VIDAS is a multi-parameter automated immunoanalyser. It comprises an analytical module, a computer and a printer. The analytical module automatically performs all stages of the analysis, including printing out the full results leaving little room for human error.

Thelma Hooper, Group Technical Microbiology Manager, commented “Customers will find that Vidas is an added choice of method whilst retaining compliance with M&S requirements. After 2 days, the Vidas system will screen out negatives, and give an indication as to the presence of Listeria monocytogenes and other Listeria spp (subject to confirmation). Even including the confirmation, the method takes no longer than standard culture. This is invaluable where a rapid result is needed, allowing product to be released with confidence.”
