Tests for the differential detection of Rotavirus, Adenovirus and Norovirus GI and GII

One-step immunochromatographic tests for the qualitative detection of Rotavirus, Adenovirus and Norovirus genogroup I (GI) and genogroup II (GII) antigens in human faeces in independent bands.

Acute gastroenteritis is the second leading cause of morbidity and mortality worldwide. Of the viruses associated with these outbreaks, rotavirus, adenovirus and norovirus are the main causative viruses in both infant and adult populations. As these are endemic viruses with a high capacity for transmission, screening should focus primarily on detection to prevent the spread of infections. On the other hand, identifying the source of the disease as early as possible, as well as differentiating whether it is a viral or bacterial infection, will allow the patient to be prescribed the most appropriate treatment and avoid the unnecessary use of antibiotics.

The OPERON Simple/Stick Norovirus, Simple/Stick Rotavirus, Simple/Stick Rota-Adeno and Simple Rota-Adeno-Noro tests allow the qualitative detection of Rotavirus, Adenovirus and Norovirus genogroup I (GI) and genogroup II (GII) antigens in human faeces in independent bands.

The Simple Rota-Adeno-Noro test allows the differentiated detection of the three main viruses causing gastroenteritis in a single test.

Differential detection of Norovirus groups I and II. Group II is the most frequent, while group I is usually associated with food poisoning and outbreaks, e.g. undercooked/processed molluscs (oysters, mussels…),cooked/processed molluscs (oysters, mussels…).

Products adapted to rapid and urgent point-of-care or POC diagnostics, with results in maximum 15 minutes, minimal handling and contact with the sample by the professional performing the test and with all components ready for use.

Control devices are available to the user to validate the results obtained. They can be purchased as a commercial independent reference.

    Frequently Asked Questions

    No, components of kits with different lot numbers should not be interchanged.

    When storing the test and/or samples under refrigeration, all kit components and faecal samples should be allowed to reach room temperature, as the use of cold reagents and/or samples may reduce the functionality of the test. To reach room temperature, it is recommended to wait 20 to 30 minutes.

    No, the kit components must not be used after the expiry date indicated.

    The reaction device should be removed from the aluminium bag only when the test is to be performed, to avoid unnecessary overexposure of the product to damaging environmental factors.

    It is very important to take the right amount of sample. If the sample is too small, very weak positive results may occur. In this case, the test should be repeated with a larger amount of sample. On the other hand, too much sample may cause the test to run too slowly and may even prevent the test from running properly.

    It is very important to add the correct volume of extracted sample to the two sample addition zones, indicated on the casing by arrows. If it is lower than indicated, the chromatography may not be performed because not enough sample reaches the reaction zones; if it is higher, brown lines may appear instead of the normal colours.

    This test is qualitative, not quantitative. However, the intensity of the positive bands is related to the amount of virus detectable in the faecal sample.

    A negative result does not exclude the possibility of Rotavirus and/or Adenovirus and/or Norovirus infection. Non-detection of these viruses may be the result of factors such as: sampling at an inappropriate time of illness (when very little virus is excreted in the faeces); incorrect storage of the sample; inadequate transport of the sample; presence of a Norovirus genotype not detected by the strip, etc.

    The test can show positive results in faeces from healthy individuals who have been administered RotaTeq oral solution up to 15 days after administration of the RotaTeq vaccine.

    A positive result does not exclude the presence of other pathogens. Co-infection of some of these three viruses with other micro-organisms may even occur. In any case, co-infections can only be clarified by differential diagnosis.

    An invalid result indicates a malfunction of the test. Some of the reasons for this may be: some of the reagents have deteriorated or the test has expired, the sample has not been prepared according to the instructions for use, or the sample has a high blood content. In case of an invalid result, it is recommended to repeat the test with a new strip strictly following the instructions for use. In the case of samples with blood, the use of an alternative technique is advised, as the problem of instabilisation does not usually depend on the strip used but on the sample matrix itself.

    The results obtained with this product will be used to support the data available from epidemiological studies, clinical evaluation of the patient and other diagnostic procedures.

    It is important to control the reaction time. If the reaction time is shorter than indicated, samples with an amount of analyte above the sensitivity limit can be clearly observed, but those at the limit will not appear. If the reaction time is longer than indicated, the sensitivity of the test will be altered, which may lead to wrong interpretations.
