Rotavirus Antigen, Feces
Use
Rotavirus is a major cause of nonbacterial gastroenteritis, especially in infants and very young children who have not received the rotavirus vaccine. Infection can range from mild to severe gastroenteritis and is more symptomatic in certain groups like preterm infants, immunosuppressed patients, and the elderly. Rapid and accurate detection of rotavirus antigens in fecal specimens aids in better patient management.
Special Instructions
Not provided.
Limitations
The presence of rotavirus antigen diminishes significantly 8 days after the onset of symptoms. A positive test does not exclude coinfection with bacterial or parasitic pathogens. Improper specimen collection or handling may result in false-negative or invalid results.
