Study Notes

Agglutination

Agglutination is a laboratory test used to detect the presence of antibodies or antigens in a sample.
The purpose of agglutination is to identify specific antibodies or antigens in a sample, which helps in diagnosing various diseases and determining blood types.

Meaning of Agglutination

Agglutination is a reaction in which particles or cells stick together, typically in the presence of an antibody.
This reaction causes the particles or cells to clump together, making them visible to the naked eye.

Slide Agglutination Test

The slide agglutination test involves mixing the antigen and antibody on a slide to observe the agglutination reaction.

Clinical Application of Agglutination

One of the most common applications of agglutination in clinical practice is in blood banking, particularly in cross-matching blood for transfusions.

ABO Blood Group System

The ABO blood group system is based on the presence of specific antigens on the surface of red blood cells.
