VANCOMYCIN-RESISTANT ENTEROCOCCI (VRE), CULTURE, SURVEILLANCE, RECTAL SWAB (SBH ONLY) - (SWAB)
Test Code: VRE
Vancomycin Resistant Enterococcus (VRE) is a culture-based test to identify carriers of VRE. The test is used to look for the presence of transferable and high-level vancomycin resistance that may be present in isolates of Enterococcus faecium and Enterococcus faecalis.
Special infection control precautions are no longer required for VRE in Manitoba and therefore, VRE screening on admission for contact management or prevalence screening purposes is no longer performed.
VRE screening may be required for admission of patients in an out-of-province facility, e.g., in the context of dialysis (during travel) or transplant.
1. VRE screening cultures must be cleared by a Microbiologist.
2. VRE screening cultures are performed at SBH only.
3. Specimens submitted for contact management or prevalence screening purposes will NOT be processed.
4. Accurate patient identification must be made prior to sample collection.
5. Sample and requisitions must be labeled/completed in accordance with the Shared Health Specimen Acceptance Policy.
Patient Preparation Instructions:
Rectal swab: carefully insert the swab ~1 in. beyond the anal sphincter. Gently rotate.
Peri-rectal swab: swab the peri-rectal area
Ostomy: swab the stoma site and place it in transport medium.
Peri-rectal swab (for pediatric patients or patients in D6 at the Health Sciences Centre)
GI ostomy swab
Swabs should be visibly soiled with fecal material. Unsoiled swabs are sub-optimal.
Peri-rectal swabs are acceptable for D6 patients at Health Sciences Center only.
Negative for VRE.
For positive samples, a descriptive report will be provided.
Store at room temperature ≤24 hours.
Specimen must be delivered to the laboratory as soon as possible and ideally within 24 hours of collection. Specimens received beyond 48 hours of collection will be processed but results may be compromised because of the prolonged transit time (a comment to this effect will be added to all negative reports).
