Carbapenem Resistant Enterobacteriaceae Culture Screen
Also known as: CRE Screen
Use
Carbapenem resistance among the Enterobacteriaceae is an emerging problem in the USA, especially on the east coast where several outbreaks have been reported. Classic screening procedures involving selective enrichments followed by traditional culture isolation step are labor intensive and turnaround time is slow. The use of selective and differential agar allows for rapid (24 hour) screening of specimens to identify the presence of carbapenem-resistant Enterobacteriaceae.
Special Instructions
Specimens should be collected prior to the initiation of antimicrobial therapy. Use transport device approved for the collection of rectal or perirectal swabs. Follow the transport device manufacturer's procedures.
