Latex agglutination test
How the test is performed:
For collection methods, see the specific topics: Depending on the item under investigation, either an antibody or antigen are attached to a latex sample. If the corresponding antigen or antibody is present, the sample agglutinates (cling together into visible particles). For example, if your health care provider suspects that your child has strep throat, a throat swab is taken, and the sample is applied to a latex sample that has antibodies against the bacteria. If your child has strep throat, that bacteria will be in the sample and will react with the antibodies on the latex causing agglutination. Latex agglutination is quick, and your health care provider should have the results in 15 minutes to an hour.
How to prepare for the test:
As with any test, your health care provider may limit certain foods or medications shortly before the test to assure accurate test results.
How the test will feel:
How the test feels depends on how the sample is collected. Please see the individual topics for information in this area.
Why the test is performed:
This test is a quick way to determine the absence or presence of an antigen or antibody. Your health care provider will base any intervention for your particular need, at least in part, on the results of this test.
