The Food and Drug Administration (FDA or Agency) is announcing the availability of a final guidance for industry entitled “Bioanalytical Method Validation.” Validation methods are completed to ensure that an analytical methodology is accurate, specific, reproducible and rugged over the specified range that a target analyte will be analyzed. Assay validation provides an assurance of reliability during normal use, and is sometime referred to as "the process of providing documented evidence that the method does what it is intended to do." Principle of the ELISA ECL Method: Though many ELISA formats exist for quantitation of proteins in complex bio-matrices, in this presentation a sandwich ELISA using electrochemiluminescene (ECL) detection is used as a model method for description of validation procedures though other ELISA detection methods such as horse radish peroxidase (HRP) reporting methods are equivalent.

Proprietary The basic enzyme-linked immunosorbent assay (ELISA), or enzyme immunoassay (EIA), is distinguished from other antibody-based assays because separation of specific and non-specific interactions occurs via serial binding to a solid surface, usually a polystyrene multiwell plate, and because quantitative results can be achieved.
