NCIt definition : A highly sensitive technique for detecting and measuring antigens or antibodies in
a solution; the solution is run over a surface to which immobilized antibodies specific
to the substance have been attached, and if the substance is present, it will bind
to the antibody layer, and its presence is verified and visualized with an application
of antibodies that have been tagged in some way. (BioTech Life Science Dictionary);
Alternative definition : CDISC: A type of enzyme immunoassay in which an antigen or antibody is bound to a
solid substrate (e.g., microplate or beads) and interacts with an enzyme-linked antibody
or antigen in solution.; NCI-GLOSS: A laboratory technique that uses antibodies linked to enzymes to detect
and measure the amount of a substance in a solution, such as serum. The test is done
using a solid surface to which the antibodies and other molecules stick. In the final
step, an enzyme reaction takes place that causes a color change that can be read using
a special machine. There are many different ways that an ELISA can be done. ELISAs
may be used to help diagnose certain diseases.;
