This test is a reverse transcription‑polymerase chain reaction (RT‑PCR) assay for the qualitative detection of norovirus genogroups I and II RNA in stool specimens. It serves as a reliable molecular method to rapidly identify norovirus as the cause of acute gastroenteritis, helping differentiate it from other causes and potentially limiting unnecessary antibiotic use and transmission in healthcare and community settings. Quest Diagnostics offers this RT‑PCR assay to provide fast and accurate diagnosis during the acute phase of illness.
