reasons for positive elisa tests
An ELISA test, or enzyme-linked immunosorbent assay, is simply a laboratory method designed to provide information on whether antigens are present in the sample. This uses enzymes and substrates in a special way that the enzyme acts on the substrate to generate an observable signal, indicating that the target molecule is there.Differentiate a direct from an indirect ELISA test.

ELISA is a biochemical assay used in immunology to detect the presence of an antigen, antibody, or another protein. It takes its name from the enzyme-linked immunosorbent assay (ELISA).. The basic principle behind ELISA is that if an antigen or antibody is present in a sample, it will bind to a specific antibody or antigen attached to a solid support.ELISA tests are categorized into three categories based on the methods applied to bind antigen and antibodies, namely: Indirect and Direct ELISA The crucial step is to immobilize the antigen of interest, which can be done directly on the test plate or indirectly via a .
What is an ELISA? 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.The enzyme-linked immunosorbent assay (ELISA) is an immunological assay commonly used to measure antibodies, antigens, proteins and glycoproteins in biological samples. Some examples include: diagnosis of HIV infection, pregnancy tests, and measurement of cytokines or soluble receptors in cell supernatant or serum.
