Helicobacter pylori is a gram-negative, microaerophilic bacterium that inhabits various areas of the stomach and duodenum. It causes a chronic low-level inflammation of the stomach lining and is strongly linked to the development of duodenal and gastric ulcers and stomach cancer. Over 80% of individuals infected with the bacterium are asymptomatic.

More than 50% of the world’s population harbour H. pylori in their upper gastrointestinal tract. Infection is more prevalent in developing countries. The route of transmission is unknown, although individuals become infected in childhood. H. pylori’s helix shape (from which the generic name is derived) is thought to have evolved to penetrate the mucoid lining of the stomach.

H. pylori Stool Antigen Test is a sandwich solid phase immunochromatographic assay. To perform the test, an aliquot of diluted stool sample is added to the sample well of the test cassette. The sample flows through a label pad containing H. pylori antibody coupled to red-colored colloidal gold. If the sample contains H. pylori antigens, the antigen will bind to the antibody coated on the colloidal gold particles to form antigen-antibody-gold complexes. These complexes move on the nitrocellulose membrane by capillary action toward the test line region on which H. pylori specific antibodies are immobilized. As the complexes reach the test line, they will bind to the antibody on the membrane in the form of a line. A second red control line will always appear in the result window to indicate that the test has been correctly performed and the test device functions properly. If H. pylori antigen is not present or lower than the detection limit of the test, only the control line will be visible. If the control line dose not developed, the test is invalid.

Rota-Adeno is a rapid, qualitative, chromatographic immunoassay which simultaneously detects rotaviruses and adenoviruses in stool samples.

Rotaviruses and adenoviruses are responsible for the majority of pediatric diarrhea cases.

Rotavirus is the primary causative agent of acute gastro-enteritis, especially in children less than 2 years old. Its discovery in 1973 and its association with infantile gastro-enteritis represented a very important advance in the study of gastro-enteritis not caused by acute bacterial infection. Rotavirus is transmitted by oral-faecal contact with an incubation period of 1-3 daysetc.

The Adenovirus is the second most common cause of viral gastro-enteritis in children (10-15%). This virus may also cause respiratory diseases and, depending on the serotype, also diarrhoea, conjunctivitis, cystitis,etc. At least 47 serotypes of adenovirus have been described, all sharing a common hexon antigen.Serotypes 40 and 41 are the ones associated with gastro-enteritis, whose main symptom is diarrhoea thatmay last between 9 and 12 days associated with temperature and vomits.

The test uses new homogenous immunochromatographic system with gold particules. It is a ready to use test which only needs a faecal sample dilution with the supplied ready to use dilution buffer. Specificity is ensured by using a monoclonal antibody conjugated with gold particules and directed against specific human genus-specific Rotavirus antigen or Adenovirus antigens. The immunochromatographic stick is coated with a polyclonal immunoreagent specific for genus-specific Adenovirus hexon antigens or rotaviurs VP6 antigen. Liquid sample and gold conjugate both migrate by capillarity and reach the first specific anti-Adenovirus polyclonal reagent. If Adenovirus is present in the sample, it is blocked and immunoreaction appears as a red-pink line. As sample still migrates, it reaches the second specific reagent line against Rotavirus,  then migrate to the non specific anti-mouse IgG which gives rise to a third red-pink line. This line indicates that the chromatography has been developed without hindrance. It appears also with negative samples.
