Vancomycin-Resistant Enterococcus, Molecular Detection, PCR
Method Description Describes how the test is performed and provides a method-specific reference
Bacterial DNA is extracted from the specimen. Using the LightCycler instrument and fluorescent energy transfer probes, vanA and vanB genes responsible for vancomycin resistance in enterococci are detected directly from perianal swabs or fecal specimens. (Sloan LM, Uhl JR, Vetter EA, et al: Comparison of the Roche LightCycler vanA/vanB detection assay and culture for detection of vancomycin-resistant enterococci from perianal swabs.

Day(s) and Time(s) Test Performed Outlines the days and times the test is performed. This field reflects the day and time the sample must be in the testing laboratory to begin the testing process and includes any specimen preparation and processing time required before the test is performed. Some tests are listed as continuously performed, which means assays are performed several times during the day.
Monday through Friday
Analytic Time Defines the amount of time it takes the laboratory to setup and perform the test. This is defined in number of days. The shortest interval of time expressed is "same day/1 day," which means the results may be available the same day that the sample is received in the testing laboratory. One day means results are available 1 day after the sample is received in the laboratory.
Maximum Laboratory Time Defines the maximum time from specimen receipt at Mayo Medical Laboratories until the release of the test result
Specimen Retention Time Outlines the length of time after testing that a specimen is kept in the laboratory before it is discarded
3 days if received in a swab transport
Performing Laboratory Location The location of the laboratory that performs the test
