Neonatal calf diarrhea is a leading cause of calf mortality worldwide and can stem from several different pathogens with overlapping symptoms, making single-pathogen testing inefficient. This 5-in-1 multiplex panel screens fecal samples for the major bovine diarrhea pathogens in one test, helping vets quickly narrow down the cause and choose appropriate treatment rather than guessing or running multiple separate tests. Shelf life is 18 months when stored at 2-30°C.
