Several types of eia tests exist validated and fda-approved eias include “elisa” (enzyme-linked immunosorbent assay) and “elfa” (enzyme-linked fluorescent immunoassay) lyme disease testing measures a person's antibody (or immune response) to the bacteria that cause lyme disease eia tests . The use of enzyme linked immunosorbent assay, or elisa, provides an economical and highly sensitive method to detect peptides, proteins or antibodies. Identifying an unknown viral pathogen requires using a transmission electron microscope because they are so small, much smaller than bacteria but, if a virus is known and can be isolated, an immunological reaction can be induced in an animal such as mice or rabbits using, then, antibodies from . Elisa- how does the test work the enzyme-linked immunosorbent assay (elisa) is a technique used to detect antibodies or infectious agents in a sample.

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.

To test for hiv, a series of blood screenings may be done, including one called the elisa test in case of a positive result, the elisa test is typically followed by an hiv differentiation assay . The western blot and elisa tests are two blood antibody tests that may be used to detect hiv in the past, the western blot test was used to confirm the results of an elisa test. Like the elisa procedure, the western blot is an antibody detection test however, unlike the elisa method, the viral proteins are separated first and immobilized.
