HEV Ab ELISA Test Background Information:
Hepatitis E is a recurring infection in developing countries. In less frequent, isolated cases, it has also been reported in developed countries. Identified in 1990, Hepatitis E (HEV) is a non-enveloped, single stranded RNA virus where infection can lead to acute (or subclinical) liver disease, like that associated to hepatitis A infection. Fatality rates are generally low - averaging 0.5-3 percent for most patients, while pregnant women hold elevated averages around 15-25 percent. In 1995 a theory was introduced that HEV was transmitted to humans from animals (zoonosis). Not long after that, in 1997 and 2001, respectively, HEV was identified as transmitted from swine and from birds. After that time, HEV infection transmission has been associated with several animals, for example, wild monkeys, deer, cow, goats, rodents, dogs, and chickens. Found in both developing and developed countries, these HEV infections (including anti-HEV) consisted of viremia and feces excretion of HEV-affected animals, such as those listed above. A direct link to acute hepatitis E in humans from eating uncooked deer meat, was also reported. Also found in supermarkets in Japan, HEV genome sequences have been identified in pork livers.


HEV Ab ELISA Test Principle:
This HEV-Ab ELISA kit uses polystyrene microwell strips pre-coated with recombinant HEV antigens (HEVAg) corresponding to structural proteins ORF-2 of the native virus. Serum or plasma sample is added into the wells. In case of presence of HEV-Ab in the sample, the pre-coated antigens will be bound to the antibody and during the first incubation step, the specific immune-complex formed is captured on the solid phase. After washing to remove unbound sample, second recombinant HEV antigen conjugated to Horseradish Peroxidase (HRP) is added into the wells. During the second incubation step, this antigen will bind to the second variable domain of the HEV antibodies if they have been captured by HEV-antigen during the first incubation step.
