Agglutination can be measured qualitatively or quantitatively. Qualitative tests simply indicate the presence or absence of agglutination, while quantitative tests measure the extent of agglutination to provide more detailed information.
- Slide Agglutination Test: A simple and rapid method where a sample is mixed with antibodies on a slide and observed for clumping.
- Tube Agglutination Test: In this method, serial dilutions of the sample are mixed with antibodies in test tubes to determine the highest dilution that still shows agglutination, providing a quantitative measure.
