The Adenovirus Rapid Test Device (Feces) is a rapid visual immunoassay for the qualitative presumptive detection of adenovirus in human fecal specimens. This kit is intended to be used as an aid in the diagnosis of adenovirus infection.
Acute diarrheal disease in young children is a major cause of morbidity worldwide and is a leading cause of mortality in developing countries. Research has shown that enteric adenoviruses, primarily Ad40 and Ad41, are a leading cause of diarrhea in many of these children, second only to the rotaviruses. These viral pathogens have been isolated throughout the world, and can cause diarrhea in children year round. Infections are most frequently seen in children less than two years of age, but have been found in patients of all ages. Further studies indicate that adenoviruses are associated with 4-15% of all hospitalized cases of viral gastroenteritis.
Rapid and accurate diagnosis of gastroenteritis due to adenovirus is helpful in establishing the etiology of gastroenteritis and related patient management. Other diagnostic techniques such as electron microscopy (EM) and nucleic acid hybridization are expensive and labor-intensive. With the self-limiting nature of adenovirus infection, such expensive and labor-intensive tests may not be necessary.
The Adenovirus Rapid Test Device (Feces) has been designed to detect adenovirus through visual interpretation of color development in the internal strip. The membrane was immobilized with anti-adenovirus on the test region. During the test, the specimen is allowed to react with colored anti-adnovirus antibodies colloidal gold conjugates, which were precoated on the sample pad of the test. The mixture then moves on the membrane by a capillary action, and interact with reagents on the membrane. If there were enough adenovirus in specimens, a colored band will form at the T region of the membrane. Presence of colored band indicates a positive result, while its absence indicates a negative result. Appearance of a colored band at the control region serves as a procedural control. This indicates that proper volume of specimen has been added and membrane wicking has occurred.

1.For professional in vitro diagnostic use only.
2.Do not use after expiration date indicated on the package. Do not use the test if its foil pouch is damaged. Do not reuse tests.
3.This kit contains products of animal origin. Certified knowledge of the origin and/or sanitary state of the animals does not totally guarantee the absence of transmissible pathogenic agents. It is therefore, recommended that these products be treated as potentially infectious, and handled observing the usual safety precautions (do not ingest or inhale).
4.Avoid cross-contamination of specimens by using a new specimen collection container for each specimen obtained.
5.Read the entire procedure carefully prior to performing any tests.
6.Do not eat, drink or smoke in the area where the specimens and kits are handled. Handle all specimens as if they contain infectious agents. Observe established precautions against microbiological hazards throughout the procedure and follow the standard procedures for proper disposal of specimens. Wear protective clothing such as laboratory coats, disposable gloves and eye protection when specimens are assayed.
7.Buffered Saline contains sodium azide which may react with lead or copper plumbing to form potentially explosive metal azides. When disposing of buffered saline or extracted samples, always flush with copious quantities of water to prevent azide build up.
8.Do not interchange or mix reagents from different lots.
9.Humidity and temperature can adversely affect results.
10.The used testing materials should be discarded in accordance with local, state and/or federal regulations.
STORAGE AND STABILITY
1.The kit should be stored at 2-30°C until the expiry date printed on the sealed pouch.
2.The test must remain in the sealed pouch until use.
3.Do not freeze.
4.Cares should be taken to protect components in this kit from contamination. Do not use if there is evidence of microbial contamination or precipitation. Biological contamination of dispensing equipments, containers or reagents can lead to false results.
SPECIMEN COLLECTION AND STORAGE
1.The Adnovirus Rapid Test Device (Feces) is intended only for use with human fecal specimens.
2.Viral detection is improved by collecting the specimens at the onset of the symptoms.
3.Perform the testing immediately after the specimen collection. Do not leave the specimens at room temperature for prolonged periods. Specimens may be stored at 2-8°C for up to 72 hours.
4.Bring specimens to room temperature prior to testing.
5.Pack the specimens in compliance with applicable regulations for transportation of etiological agents, in case they need to be shipped.
