In this technique, the antigens in the sample distribution bind with the immobilized antibodies connected a solid surface.
That usually happens because of some antibodies that were manageable against other organisms recognizing part of hiv.
Elisa has been used commonly in-home pregnancy tests and in the food for thought industry to notice food allergens so much as walnuts, peanuts, milk, almond and eggs.
This procedure testament produce an competent but less precise.
In the elisa exam, an enzyme golf links to the antibodies particularly to discover the presence of proteins like antigens.

What do you need to know about the ELISA test?
Medically reviewed by Timothy J. Legg, PhD, CRNP on June 22, 2017 — Written by Tricia Kinman. An enzyme-linked immunosorbent assay, also called ELISA or EIA, is a test that detects and measures antibodies in your blood. This test can be used to determine if you have antibodies related to certain infectious conditions.
How are HIV antibodies measured in an ELISA test?
In this test, a person's serum is allowed to react with virus proteins that have been produced in the laboratory. If the person has been infected with HIV, the antibodies in the serum will bind to the HIV proteins, and the extent of this binding can be measured.
How is the enzyme linked immunosorbent assay ( ELISA ) used?
The enzyme-linked immunosorbent assay (ELISA) (/ɪˈlaɪzə/, /ˌiːˈlaɪzə/) is a commonly used analytical biochemistry assay, first described by Weiland in 1978. The assay uses a solid-phase enzyme immunoassay (EIA) to detect the presence of a ligand (commonly a protein) in a liquid sample using antibodies directed against the protein to be measured.
Which is more sensitive ELISA or RIA test?
ELISA test is being increasingly used in the detection of antigen (infectious agent) or antibody due to its simplicity and sensitivity. It is as sensitive as radioimmunoassay (RIA) and requires only microlitre quantities of test reagents.
