Overview
The Adenovirus Antigen for Gastroenteritis Stool Test is performed to detect the presence of adenovirus antigens in a patient's stool sample, thereby confirming adenovirus as the causative agent of acute gastroenteritis. This test aids clinicians in differentiating adenoviral gastroenteritis from bacterial, parasitic, or other viral causes of diarrheal illness, guiding appropriate management and helping prevent unnecessary use of antibiotics. It is particularly valuable in pediatric populations, immunocompromised patients, and outbreak settings where rapid identification of the infectious agent is critical for patient care and public health response.

Sample Collection
No special preparation, fasting, or dietary restrictions are required before collecting the stool sample. Inform your physician about any medications, particularly antiviral agents, that you are currently taking.
Method: Patient-collected stool sample
Laboratory Analysis
Collect approximately 5 grams of fresh stool (about the size of a walnut) into the provided sterile screw-capped container. Avoid contamination with urine, water, or toilet bowl cleaner. Ensure the container lid is tightly sealed.
Report Delivery
Label the container with your name, date, and time of collection. Refrigerate the sample immediately at 2–8°C. Do not freeze the sample. Transport the sample to the laboratory or hand it to the collection agent as soon as possible.
Timeline: Same-day reporting for samples received by 1:00 PM at the laboratory.

Doctor's Notes
Reviewed by Dr Kothari Ramesh Shantilal — MBBS, MD (Microbiology) · Reg. No. 27670
"Adenovirus is a recognized cause of acute gastroenteritis, especially in children under 5 years of age. Stool antigen testing provides a rapid, non-invasive method for confirming adenoviral infection, enabling timely supportive care and appropriate infection control measures. If symptoms persist beyond 7–10 days or are accompanied by high fever, dehydration, or bloody stools, immediate medical consultation is strongly recommended."

Test Parameters & Specifications
Sample Stability
- Stool sample collected in a non-sterile or leaking container
- Frozen stool sample
- Sample received at room temperature more than 2 hours after collection
- Sample contaminated with urine, water, or other foreign substances
- Insufficient sample quantity (less than the required 5 grams)
- Unlabeled or improperly labeled specimen containers
Understanding Your Results
Positive (Detected)
Adenovirus antigens have been detected in the stool sample, confirming adenovirus gastroenteritis. This result indicates that adenovirus is the likely cause of the patient's gastrointestinal symptoms. Supportive treatment including hydration and electrolyte replacement is recommended. Consult your physician for further management.
Negative (Not Detected)
No adenovirus antigens were detected in the stool sample. This may indicate that the patient's gastroenteritis is caused by an infectious agent other than adenovirus, or that viral shedding has ceased. If clinical suspicion remains high, repeat testing or additional diagnostic workup may be recommended by your physician.
Indeterminate / Equivocal
The test result is inconclusive. A repeat stool sample may be required for definitive diagnosis. Clinical correlation and consultation with your treating physician are advised.
Consult a doctor if you experience persistent diarrhea lasting more than 3 days, signs of dehydration (dry mouth, reduced urination, dizziness), high fever (above 102°F / 39°C), blood in stool or vomit, severe abdominal pain, or if symptoms occur in infants, elderly individuals, or immunocompromised patients. Immediate medical attention is warranted if the patient is unable to tolerate oral fluids.
Limitations
- ⚠This test detects adenovirus serotypes 40 and 41 (enteric types) and may not reliably detect all adenovirus serotypes
- ⚠A negative result does not completely rule out adenovirus infection, as viral shedding may be intermittent
- ⚠The test cannot determine the specific adenovirus serotype; further testing such as PCR or viral culture is required for serotyping
- ⚠This test is a qualitative screening assay and does not quantify the viral load in the stool
- ⚠Results should always be interpreted in conjunction with clinical symptoms and patient history
Risks & Considerations
- ●This test involves no invasive procedures and carries no physical risk
- ●There is a small possibility of false-negative results, particularly if the sample is collected late in the course of infection
- ●False-positive results are uncommon but possible; clinical correlation is always recommended
Interfering Factors
- ●Specimen collected more than 7 days after symptom onset may yield false-negative results due to declining viral shedding
- ●Improper specimen storage (freezing or prolonged room-temperature exposure) can degrade antigens and affect accuracy
- ●Stool specimens contaminated with urine, water, or toilet paper may interfere with test performance
- ●Recent use of antiviral medications may reduce viral load and potentially affect antigen detection
- ●Formed or hard stool specimens may have lower viral antigen concentration compared to liquid or loose stools
