INMUNOENSAYO [7 records]

Record 1 2023-03-30

English

Subject field(s)
  • Bioengineering
  • Immunology
DEF

The use of antibodies, with a fluorescent marker dye attached, in order to detect whereabouts of specific antigens ... by formation of antibody-antigen complexes which show up on appropriate illumination.

OBS

The direct method utilizes a fluorochrome conjugated to an antibody, which is added directly to a tissue or cell suspension for the detection of a specific antigen. The indirect method permits detection of an antigen with a non-fluorochrome-conjugated antibody.

OBS

immunofluorescence method: This term appears under the entry "method" in the Stedman's medical dictionary.

Spanish

Campo(s) temático(s)
  • Bioingeniería

Subject field(s)
  • Immunology
  • Diagnostic Procedures (Medicine)
DEF

[An] immunoassay in which an enzyme is used as a marker to indicate the presence of specific antigens, [or] antibodies ...

CONT

Several enzyme immunoassays (EIA) have been developed commercially to detect IgG [immunoglobulin G] or IgM [immunoglobulin M] to specific T. [Treponema] pallidum antigens and are useful in HIV co-infected patients.

English

Subject field(s)
  • Diagnostic Procedures (Medicine)
  • Immunology
  • Biotechnology
DEF

[An] enzyme immunoassay utilizing an enzyme-labeled immunoreactant (antigen or antibody) and an immunosorbent (antigen or antibody bound to a solid support).

CONT

ELISA is widely used for diagnostic and other purposes.

DEF

Essai immunoenzymatique fondé sur la fixation (adsorption) d'un anticorps ou d'un antigène sur une matrice, par exemple, une microplaque.

CONT

Le test ELISA [...] est un test immunologique destiné à détecter [ou à] doser une protéine dans un liquide biologique. [...] C'est le type de test utilisé notamment pour le dépistage de la séropositivité au virus VIH, c'est-à-dire pour mettre en évidence la présence d'anticorps anti-VIH dans le sérum.

DEF

Estudio inmunológico de laboratorio por medio de reactivos para detectar diversos gérmenes, tales como virus o protozoarios, mediante la detección de anticuerpos específicos contra ellos o alguno de sus antígenos.

CONT

La prueba de ELISA no establece un diagnóstico de sida ni es un pronóstico del avance de la enfermedad.

OBS

ELISA por sus siglas en inglés "enzyme-linked immunosorbent assay".

Record 4 2007-07-31

English

Subject field(s)
  • Immunology
DEF

A type of immunoassay in which the ligand is labelled with an enzyme, and the enzyme-ligand-antibody complex is enzymatically inactive, allowing quantitation of unlabelled ligand.

OBS

The test uses antibodies that react only with the particular drug for which the sample is being tested. The antibodies attach themselves to the drug if it is present in the sample. It is not designed to measure amounts of the drug present, only to detect its presence or absence. It is used predominantly, but not exclusively, for the detection of drugs of abuse in the urine.
