Clinical Significance

Diagnose norovirus associated gastroenteritis
Norovirus, also called Norwalk-like virus, is a major cause of viral gastroenteritis and has been associated with many close-contact outbreaks including in hospitals, schools, cruise ships, and residential homes. Detection of Norovirus antigen is important for patient and public health management and helps to provide diagnosis of the gastroenteritis. A positive EIA result indicates the presence of Norovirus antigen, but does not differentiate genotype 1 and 2.
