Understanding Your Results
Positive

Recommendation: Initiate supportive care, oral rehydration, and follow up with healthcare provider.
Negative

Recommendation: Consider other causes of gastroenteritis and repeat testing if clinically indicated.
If you or your child experiences persistent diarrhea, vomiting, high fever, or signs of dehydration (e.g., decreased urine output, dry mouth, sunken eyes, lethargy), seek medical attention immediately.
