Norovirus test is a qualitative in vitro diagnostic test for the identification and differentiation of Norovirus genogroup I (GI) and genogroup II (GII) from raw or unpreserved unformed stool specimens collected from individuals with symptoms of acute gastroenteritis. Noroviruses classified into these two genogroups cause majority of the infections in human. The test utilizes real-time reverse transcriptase polymerase chain reaction (RT-PCR) to detect norovirus RNA. CDC guidelines recommend submitting stool specimens as early as possible during a suspected Norovirus gastroenteritis outbreak and ideally from individuals during prodromal or acute phase of illness (within 2-3 days of onset of symptoms).Common names associated with norovirus gastroenteritis are winter vomiting disease, stomach flu, acute nonbacterial gastroenteritis, and viral gastroenteritis.
