ANTIBODY TEST [19 records]

Record 1 2023-03-30

English

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

A diagnostic test that allows the detection of a specific microorganism through the use of a specific fluorescently labeled antibody that reveals its antigen counterpart.

CONT

The first test [performed on the sample], a direct fluorescent antibody test (DFA), looked for whole, visible Legionella cells with a fluorescent microscope that could see the stained cells. This test was negative for Legionella.

DEF

Épreuve de laboratoire qui repose sur l'utilisation d'un anticorps spécifique couplé à un fluorochrome pour détecter la présence d'un microorganisme donné, c'est-à-dire de son antigène.

Record 2 2023-03-30

English

Subject field(s)
  • Diagnostic Procedures (Medicine)
  • Bacterial Diseases
DEF

A blood serum screening test for syphilis designed to demonstrate the presence or absence of specific antibodies directed against the organism (Treponema pallidum) responsible for syphilis.

OBS

The "fluorescent treponemal antibody absorption test" is a Treponema-specific test.

OBS

... the test serum is absorbed with nonpathogenic treponemal organisms before incubation with fixed Treponema pallidum. This removes antibodies reactive with other organisms and leaves antibodies specifically indicative of a syphilitic infection.

OBS

FTA-ABS test: This term appears under the entry "test" in the International dictionary of medicine and biology.

Key term(s)
  • fluorescent treponemal antibody-absorption test

French

Domaine(s)
  • Méthodes diagnostiques (Médecine)
  • Maladies bactériennes
CONT

Tests sérologiques de la syphilis [...] Il existe trois tests tréponémiques standard [dont] l'immunofluorescence (FTA-ABS)[.] Pour le test FTA-ABS, le sérum du malade est d'abord dilué avec une substance contenant des antigènes tréponémiques non pathogènes (absorbant) pour éliminer les anticorps spécifiques de groupe dirigés contre les tréponèmes saprophytes des cavités buccales et génitales. Le sérum ainsi absorbé est alors déposé sur une lame recouverte de T. [Treponema] pallidum fixés. Si l'anticorps spécifique de T. Pallidum est présent dans le sérum du patient, il se fixe aux tréponèmes séchés; sa mise en évidence se fait alors par l'adjonction d'anti-immunoglobulines humaines marquées à la fluorescine et examen de la lame au microscope à fluorescence. [...] le FTA-ABS [est un test très spécifique, et lorsqu'il est utilisé] pour confirmer des réactions réaginiques positives, [il a] une très haute valeur prédictive positive pour le diagnostic de la syphilis.

Record 3 2023-03-30

English

Subject field(s)
  • Diagnostic Procedures (Medicine)
  • Bacterial Diseases
DEF

A test for specific antitreponemal antibodies in the serum of a patient who has had syphilis.

OBS

After the serum is incubated with a slide preparation of fixed treponemal organisms, a fluorescence-labeled antiglobulin serum is added to demonstrate whether antibodies have attached to the organisms.

OBS

fluorescent treponemal antibody test; FTA test: These terms appear under "test" in the International dictionary of medicine and biology.

French

Domaine(s)
  • Méthodes diagnostiques (Médecine)
  • Maladies bactériennes
OBS

L'acronyme «FTA» vient de l'anglais «fluorescent treponemal antibody». Le test FTA permet de détecter par immunofluorescence la présence dans le sérum sanguin d'anticorps dirigés contre les tréponèmes, qui comprennent notamment la bactérie responsable de la syphilis.

CONT

Antibody detection tests. An alternative approach to diagnosing infections is to look for a specific host response to infection, rather than detect the pathogen itself. The most common means of doing this is to measure antibodies in patient serum. The detection of (for example) SARS-CoV-2 [severe acute respiratory syndrome coronavirus 2] antibodies does not indicate that a patient has ongoing infection, but rather that they have been exposed to the virus at some point in the past.

OBS

Antibody tests are usually done on a sample of the infected person's blood. They also can be done on samples of cerebrospinal fluid or other body fluids.

The rabies antibody test is indicated for individuals who because of high risk exposure to possibly rabid animals have been previously immunized against the virus. This population typically includes veterinarians, animal control officers, laboratory personnel and other workers who come in frequent contact with potentially rabid animals. The result of this test will determine if an individual has had a successful sero-conversion after immunization.
