When the specific antibodies (agglutinins) bind to surface antigens of bacteriavirus or any antigens immobilized in particulate matter (such as latex particle) and cause the formation of a visible clumps, such test is called agglutination test.A slide latex agglutination test for the identification of Staphylococcus aureus from culture media. Tests for both the Clumping Factor and Protein A found in Staphylococcus aureus. Clumping Factor is detected in both free and bound form. Blue latex on white card for easy readout. agglutination tests pdf

agglutination test used to detect the presence of an antigen or an antibody. The antibody is mixed with the particulate antigen and a positive test is indicated by

The latex agglutination test is a laboratory method to check for certain antibodies or antigens in a variety of body fluids including saliva, urine, cerebrospinal fluid, or blood. Using the slide agglutination method, determine with 100 accuracy the ABO group of specimens using reagent antiseras, blood specimens, and other materials provided. 2. agglutination tests pdf Agglutination tests. In agglutination tests, an antigen reacts with its corresponding antibody, resulting in visible clumping of bacterial cells. With latex agglutination tests, latex particles are coated with antibodies that agglutinate specific antigens and form a more easily visible precipitate.

agglutination is directly observable to the naked eye as a clumping reaction. This exercise involves 2 kinds of serological testsone for the identification of an unknown antigen and the other for the identification of an unknown antibody. agglutination tests pdf Perform latex agglutination tests for the detection of rheumatoid factor to obtain control and patient results that match instructor values with 100 accuracy. 3. Feb 14, 2010 Positive and negative predictive values of latex agglutination test were 6 and 100, respectively. Due to inconvenient sensitivity and specificity of the latex agglutination test developed in this study, further work is recommended to improve the test. Agglutination tests can be used in a qualitative manner to assay for the presence of an antigen or an antibody. The antibody is mixed with the particulate antigen and a positive test is indicated by the agglutination of the particulate antigen. In addition to bacterial isolation, serological tests can be performed. CDC utilizes a test called the Brucella microagglutination test (BMAT), a modified version of the serum (tube) agglutination test (SAT), that can detect antibodies to Brucella species abortus, melitensis or suis. There is no serological test available to detect antibodies to B. canis.
