Key result
POCKIT system detects norovirus with ~100% specificity and high sensitivity compared to conventional rRT-PCR.
Why the study?
Norovirus is a leading cause of acute gastroenteritis in Taiwan, and improved diagnostic methods were needed for laboratory surveillance of outbreaks.
Does the POCKIT system accurately detect norovirus in clinical stool samples compared to conventional rRT-PCR?
Cross-Sectional (n=119)
Does the POCKIT system accurately detect norovirus in clinical stool samples compared to conventional rRT-PCR?
The POCKIT system provides a highly sensitive and specific, faster, and easier-to-use alternative to conventional rRT-PCR for near real-time surveillance of norovirus outbreaks.

May enable faster norovirus surveillance; leaves open prospective validation before clinical adoption.
Norovirus is a leading cause of acute gastroenteritis (AGE) in Taiwan. To improve diagnosis as part of laboratory surveillance, AGE surveillance was conducted using a new fluorescent probe hydrolysis-based insulated isothermal polymerase chain reaction (PCR) method, the POCKIT system, and the results were compared with those obtained from conventional methods. A total of 119 clinical stool samples from reported AGE outbreaks were collected for this study. From 83 real-time reverse transcription PCR (rRT-PCR) norovirus-positive cases, the POCKIT system identified 78 with a sensitivity of 90.3% in GI genogroup and 96.7% in GII genogroup. The specificity for both GI and GII genogroups was 100%. Overall, the POCKIT system is faster and easier to use than the conventional rRT-PCR method, and because of its high sensitivity and specificity, this system is a promising alternative for the detection of norovirus in patients with AGE, and would benefit public health laboratories for near real-time surveillance of AGE epidemic outbreaks.

Chiu et al. (2022) conducted a cross-sectional in Acute gastroenteritis (AGE) / Norovirus (n=119). POCKIT system vs. Conventional real-time reverse transcription PCR (rRT-PCR) was evaluated on Sensitivity and specificity for norovirus GI and GII genogroups. The POCKIT system detected norovirus with 90.3% sensitivity for GI, 96.7% for GII, and 100% specificity for both genogroups compared to conventional rRT-PCR.
