In published implementation studies, Xpert Norovirus PCR testing has been evaluated in routine healthcare settings to assess its potential role in supporting timely laboratory diagnosis. These studies report that fast molecular results may support infection control workflows when used as part of established institutional practices.³ ⁵ ⁶ Across reported study sites, implementation of Xpert Norovirus testing was associated with reduced laboratory turnaround times compared to prior diagnostic approaches under those specific conditions. Reported findings included:
- An 89% reduction in turnaround time (from 22 hours to 2.4 hours) within the evaluated study settings⁵
- A reported reduction in unnecessary patient isolation when molecular testing results were incorporated into local infection management decisions⁶
- Estimated operational cost impacts related to bed availability and isolation practices, as described in site‑specific economic analyses⁶
- These outcomes reflect observations from published studies conducted in defined healthcare environments and may vary based on institutional workflows, infection control policies, patient populations, and local resource availability.
