Particle Agglutination Test Essay
~ The antigen-antibody complexes can be enlarged using the latex particles. Many of the latex agglutination tests are performed manually and detected by visual observation. To determine agglutination, clumps must be present, and these clumps must be micrometer in size to be visible to the eye. Agglutination, latex agglutination test is a very rapid, accurate and specific method used to diagnose antigens and antibodies. This method can be performed anywhere without the need for any specific equipment. In the present study, a scFv recombinant single-chain monoclonal anti-K was used in the design and production of a latex. We validated the antibody test based on agglutination of latex particles by plasma samples tested positive for SARS-CoV-NAAT, which were NAAT-negative, SARS-CoV-2-naïve plasma samples. The agglutination-based antibody test, specificity -98.2, in-house ELISA was used as a screening procedure, and a particle agglutination test was used to reassess antibody titers. ml or less. Agglutination tests to detect antigens use solid hemagglutination of red blood cells, latex beads, gelatin or synthetic microbeads coated with specific antibody as carrier or indicator particles. A typical agglutination test for the detection of microbial antigen involves applying a drop of liquid suspension of antibody-coated particles.

Post-h latex agglutination is a relatively rapid, simple test with a reasonable overall sensitivity 66 for detection of GBS carriage and a high sensitivity for heavy and moderate carriage, respectively 100 8, which is directly associated with the risk of serious neonatal diseases. fair sensitivity 34 false negative, hour time, Illustration of the principle of agglutination test for SARS-CoV testing A Latex particles or red blood cells are covered on the surface with a SARS-CoV - S-RBD or nucleocapsid. We previously reported the development of a new rapid test method based on ultrasonic particle agglutination UPA, 14, 15 which has been shown to be - more sensitive than the Capillus agglutination-based, Multispot microparticle immunoconcentration-based and Uni-Gold Recombigen lateral flow .
