A screening test that detects the presence of antibodies in a person’s body by testing serum (blood or oral fluid). The body’s immune system produces these antibodies when infected with microorganism or foreign body

There are three types of results you could possibly receive from a Rapid test:
A Reactive or Preliminary Positive Result: This means antibodies were detected in your body. A confirmatory test will be given to eliminate the chance of a false positive result.

A Non-reactive or Negative Result:
A non-reactive or negative result means that the test did not detect any antibodies.

An Invalid Result:
This means that the foreign body cannot be interpreted. An invalid test result means there was a problem running the test, either related to the test device or the specimen. In this case, another test would be given.



veda-lab-1Latex agglutination tests have been in use to detect a wide range of analytes in the clinical laboratory. The first descriptionof a test based in latex agglutination was the Rheumatoid Factor Test proposed by Singer and Plotz in 1956. In latex agglutination procedures, an antibody (or antigen) coates the surface of latex particles (sensitized latex). When a sample containing the specific antigen (or antibody) is mixed with the milky-appearing sensitized latex, it causes visible agglutination. The degree of agglutination plotted as a function of agglutinant concentration follows a bell-shape curve similar to the precipitin one. Latex particles are used to magnify the antigen-antibody complex.
