Key result
The RIDASCREEN norovirus ELISA kit demonstrated a sensitivity of 76.3% and a specificity of 94.9% compared to RT-PCR for detecting norovirus in stool samples from infants and children.
Why the study?
Does a commercial norovirus ELISA kit accurately detect norovirus antigens in stool samples of infants and children with acute gastroenteritis compared to RT-PCR?
Observational (n=503)
Yes
Does a commercial norovirus ELISA kit accurately detect norovirus antigens in stool samples of infants and children with acute gastroenteritis compared to RT-PCR?
The commercial norovirus ELISA kit shows high specificity but moderate sensitivity, requiring improvements for detecting GII/3 and GII/6 genotypes.
Answers are grounded in this paper and cite their sources.
High specificity supports ruling in norovirus; moderate sensitivity leaves open need for RT-PCR confirmation or assay refinement in children.
The commercial norovirus enzyme-linked immunosorbent assay kit was evaluated for its reactivity to recombinant virus-like particles and the detection of natural viruses from stool samples of Japanese infants and children with sporadic acute gastroenteritis compared to reverse transcription-PCR. The kit had a sensitivity of 76.3% and a specificity of 94.9%. Our results clearly indicated that the kit allows the detection of the most prevalent genotype, GII/4. In order to increase the sensitivity of the kit, the reactivity with norovirus of GII/3 and GII/6 genotypes needs to be improved.

Okitsu‐Negishi et al. (2006) conducted an observational in Sporadic acute gastroenteritis (n=503). RIDASCREEN norovirus ELISA kit vs. RT-PCR was evaluated on Diagnostic sensitivity and specificity for norovirus detection (Sensitivity 76.3%, Specificity 94.9%). The RIDASCREEN norovirus ELISA kit demonstrated a sensitivity of 76.3% and a specificity of 94.9% compared to RT-PCR for detecting norovirus in stool samples from infants and children.
