General Information

Useful for:


Specimen Type

Stool

Specimen Requirements

Sterile Container

Stability

  • Frozen (preferred): 7 days

  • Refrigerated: 72 hours

Unacceptable Specimen Conditions

  • Grossly bloody (containing no visible feces)

  • Very mucoid feces

Limitations

  • Fecal specimens should be collected as soon after onset of symptoms as possible

  • Do not collect specimens in containers having media, preservatives, animal serum, or detergent as any of these may interfere with the assay

  • A positive result does not preclude the presence of other pathogenic organisms. While the relationship between rotavirus and gastroenteritis is well established, coinfection with bacterial or parasitic pathogens is possible. If suspected, testing for other enteric pathogens should be performed in parallel with the rotavirus antigen test

  • Results of the rotavirus antigen assay must be interpreted with caution. A negative result does not exclude the possibility of rotavirus infection, as too small a quantity of virus or inadequate or improper sampling may cause a false-negative result
