RIDASCREEN® Adenovirus IgA
Product Code. K1011
Intended use:
For in vitro diagnostic use. The RIDASCREEN® Adenovirus IgA test is an enzyme immunoassay for the semi-quantitative determination of IgA antibodies against adenoviruses in human serum. The test should be used for confirmation purposes when there is a suspected case of infection with adenoviruses or for clarifying the immune status.
General information:
After infection with adenoviruses, specific antibodies are formed
against the pathogen as a re-sult of the response from the immune
system. By using immunological methods, it is possible to determine the
antibodies in the serum. The test method used and the choice of the
pathogen-specific antigen both have a significant bearing on the
meaningfulness of the test. Because it is possible to differentiate
between the individual immunoglobulin classes in the enzyme
immuno-assay, more precise statements about the immunological status of
a patient can be made than those which are based on other serological
methods (such as the haemagglutination inhibition test or the
complement fixation test).
Test principle
Purified antigens are coated to a microwell plate. Antibodies in
the patient samples bind to the antigens and are determined during the
second incubation step by using enzyme-labelled anti-human antibodies
(the conjugate). The enzyme converts the colourless substrate (H2O2/TMB)
to a blue end product. The enzyme reaction is stopped by adding
sulphuric acid and the colour of the mixture switches from blue to
yellow at the same time. The final measurement is carried out at 450 nm
on a photometer using a reference wavelength ≥ 620 nm.
With ocular or intestinal infections, the immune response can be to
low for antibody detection. In such cases, a direct antigen detection
is recommended.
Please also pay attention to our ELISA for antigen detection in case of intestinal Adenovirus infection (Art. No.: C 1001).
