Limitations
- ⚠Screening test detects VRE colonization, not antibiotic susceptibility.
- ⚠Negative result does not rule out VRE infection at another body site.
- ⚠Poor sample quality or delayed transport can cause false-negative results.
Risks & Considerations
- ●Minor discomfort during swab collection
- ●Very low risk of bleeding if the wound site is friable
Interfering Factors
- ●Recent antibiotic therapy, especially with vancomycin, may reduce organism recovery.
