Rotavirus & Adenovirus Test: How to Detect Stomach Flu at Home
The Rotavirus & Adenovirus Test from The Tester is a CE-certified home stool test that detects both rotavirus and adenovirus in a single test cassette โ giving you a reliable result within 15 minutes. If you or your child has sudden diarrhoea, vomiting, and fever, this combo test helps you identify the viral cause of gastroenteritis without a lab visit.
What Are Rotavirus and Adenovirus?
Rotavirus
Rotavirus is the leading cause of severe diarrhoea in infants and young children worldwide. It spreads easily through the faecal-oral route โ contaminated hands, surfaces, and objects. Symptoms include watery diarrhoea, vomiting, fever, and abdominal pain. While a vaccine exists, breakthrough infections can still occur, and adults can also be affected (often with milder symptoms).
Adenovirus (Enteric Types 40/41)
Enteric adenoviruses are a common but often overlooked cause of gastroenteritis, particularly in children under 2 years old. They cause prolonged diarrhoea (often lasting 5โ12 days), along with low-grade fever and vomiting. Adenovirus gastroenteritis occurs year-round, unlike rotavirus which peaks in winter months.
Symptoms: When Should You Test?
Consider using the Rotavirus & Adenovirus Test if you or your child experiences:
- Sudden watery diarrhoea โ especially in children under 5
- Vomiting combined with diarrhoea โ the classic gastroenteritis pattern
- Fever with abdominal cramps
- Dehydration signs โ dry mouth, reduced urination, lethargy
- Symptoms lasting more than 2โ3 days โ especially in young children or elderly adults
- After contact with someone with confirmed gastroenteritis
Important: Rapid identification helps you take the right steps sooner โ rotavirus and adenovirus are viral (antibiotics wonโt help), so treatment focuses on hydration and symptom management.
How Does the Test Work?
The test uses immunochromatographic technology to detect viral antigens in a stool sample. The single test cassette contains two separate test strips โ one for rotavirus and one for adenovirus โ so you get both results from one sample.
Step-by-Step
- Collect a small stool sample using the included collection stick and paper strip
- Mix the sample with the extraction solution in the collection tube
- Add a few drops of the mixture to the test cassette
- Wait 10 minutes and read the result within 15 minutes
Interpreting Results
| Result | Lines Visible | Meaning |
|---|---|---|
| Rotavirus Positive | C + T (ROTA strip) | Rotavirus infection detected |
| Adenovirus Positive | C + T (ADEN strip) | Adenovirus infection detected |
| Both Positive | C + T on both strips | Co-infection with both viruses |
| Negative | C line only (both strips) | No rotavirus or adenovirus detected |
| Invalid | No C line | Test failed โ contact customer service |
Accuracy and Reliability
- Rotavirus detection: over 97% accuracy
- Adenovirus detection: over 99% accuracy
- CE-certified for professional and home use
- Immunological testing method used worldwide in hospitals and clinics
What to Do After Your Result
Positive Result
- Focus on hydration: Oral rehydration solutions (ORS) are the most important treatment, especially for children
- Consult a doctor if the patient is very young, elderly, immunocompromised, or showing signs of severe dehydration
- Practice strict hygiene: Rotavirus and adenovirus are highly contagious โ wash hands frequently, disinfect surfaces, and keep the infected person isolated if possible
- No antibiotics: These are viral infections; antibiotics are ineffective
Negative Result
- Rotavirus and adenovirus were not detected, but other causes of gastroenteritis exist (norovirus, bacterial infections, food poisoning)
- If symptoms persist or worsen, consult your doctor for further investigation
- Consider additional gut health testing such as the Gut Health Test (Calprotectin & FOB) to check for intestinal inflammation
Rotavirus vs. Adenovirus: Key Differences
| Feature | Rotavirus | Adenovirus (Enteric) |

Frequently Asked Questions
Can adults get rotavirus and adenovirus?
Yes. While children are most commonly and severely affected, adults can contract both viruses โ especially when caring for infected children, travelling, or when immunocompromised. Adults tend to have milder symptoms but are still contagious.
How contagious are rotavirus and adenovirus?
Extremely contagious. Both viruses can survive on surfaces for hours to days and spread through the faecal-oral route. Just a tiny number of viral particles can cause infection. Thorough handwashing, surface disinfection, and isolating contaminated items are essential.
Is this test suitable for babies and toddlers?
Yes. The test only requires a small stool sample, which parents can collect from a nappy/diaper. Itโs a non-invasive way to quickly check whatโs causing your childโs symptoms.
Why test at home instead of going to the doctor?
Home testing provides immediate clarity โ within 15 minutes you know whether a rotavirus or adenovirus is the cause. This helps you make faster decisions about hydration therapy and whether a doctor visit is needed. It also reduces the risk of spreading the virus in a waiting room.
What if the test is negative but symptoms continue?
A negative result means rotavirus and adenovirus were not detected. Other causes like norovirus, bacterial infections (Salmonella, Campylobacter), or food intolerance may be responsible. Consult your doctor for further investigation if symptoms persist beyond 3โ5 days.
Should I still see a doctor after a positive result?
Yes, especially for children under 5, elderly adults, or anyone with signs of dehydration (sunken eyes, dry mouth, no tears, reduced urination). While most viral gastroenteritis resolves on its own with fluids and rest, severe cases may require medical intervention.
How should I store the test?
Store at 4โ30ยฐC. Do not freeze. Check the expiry date before use. The test should be used within the indicated time after opening the sealed aluminium pouch.
