ELISA stands for "enzyme-linked immunosorbent assay." This is a rapid immunochemical test that involves an enzyme (a protein that catalyzes a biochemical reaction). It also involves an antibody or antigen (immunologic molecules). ELISA tests are utilized to detect substances that have antigenic properties, primarily proteins (as opposed t [..]

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 antibodi [..]

Immunodiagnostic test designed to detect the presence of fixed antibody through linkage with an enzymatic reaction. enzymes

A technique using antibodies for detecting specific proteins. Used to test for the presence of a particular genetically engineered organism.

The ELISA is a fundamental tool of clinical immunology, and is used as an initial screen for HIV detection. Based on the principle of antibody-antibody interaction, this test allows for easy visualiza [..]

Enzyme-linked immunosorbent assay (ELISA), is a biochemical method used in the laboratory to aid in the diagnosis of several medical conditions by detecting the presence of antibodies or antigens in t [..]

A laboratory test to detect the presence of HIV antibodies in the blood, oral fluid, or urine. The immune system responds to HIV infection by producing HIV antibodies. A positive result on an enzyme-linked immunosorbent assay (ELISA) must be confirmed by a second, different antibody test (a positive Western blot) for a person to be definitively dia [..]

An immunoassay utilizing an antibody labeled with an enzyme marker such as horseradish peroxidase. While either the enzyme or the antibody is bound to an immunosorbent substrate, they both retain thei [..]

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. T [..]

A technique using antibodies for detecting specific proteins. It is used to test for the presence of a particular genetically engineered organism.

A type of test in which subclasses of immunoglobulins may be detected; the test is helpful in diagnosing some autoimmune diseases such as Celiac Disease, lupus, rheumatoid arthritis, viral illness and many others.
