Slide agglutination test principle procedure

The Slide Agglutination Test is a widely used technique in microbiology that leverages the principles of antigen-antibody interactions for the rapid detection of specific substances in the samples.

Slide Agglutination Test principle

Latex particles coated with specific antibodies or antigens are mixed with a sample. If the sample contains the matching antigen or antibody, clumping (agglutination) occurs on a glass slide.

Slide Agglutination test procedure

  • Preparation of Latex Reagent: If the reagent is not prepared then latex particles are mixed with specific antibodies or antigens specific to the target substance.
  • Sample Collection: The sample (such as serum, blood, or other bodily fluids) is collected.
  • Mixing of Latex Reagent and Sample: Now add a small volume of the prepared latex reagent is mix it with the sample on a glass slide. The mixture is gently agitated to ensure thorough interaction between the sensitized latex particles and the target antigen or antibody in the sample.
  • Agglutination is observed directly on the glass slide under a macroscopic examination.

Result Interpretation

  • Agglutination indicates a positive result in the presence of the target antigen or antibody.
  • The negative result shows no agglutination.
