OBJECTIVE: Effects of RIDASCREEN Norovirus (C 1401) 3rd Generation kit (R-biopham AG, darmstadt, Germany) and IDEIA NLV kit (DAKOCytomation., Ely, UK) were compared for detecting human norovirus (HuNV) in fecal sample. METHODS: The performance of the ELISA was compared with that of the reverse transcription polymerase chain reaction (RT-PCR) by testing a panel of 308 fecal samples collected from patients involved in outbreaks of gastroenteritis in Chang Chun and Guang Zhou. Gene sequencing was performed to positive samples tested by RT-PCR to determine genotype compared with standard sequences. RESULTS: RT-PCR is gold standard, RIDASCREEN Norovirus (C 1401) 3rd Generation kit had a high sensitivity of 96.10% but a specificity of 93.51%, and Dako kit had a low sensitivity of 95.83% but a high specificity of 95.76%. CONCLUSION: RIDASCREEN Norovirus (C 1401) 3rd Generation kit is more Satisfactory for a preliminary screening.
