Determining the Reactivity and Titre of Serum using a Haemagglutination Assay

¹School of Pharmacy and Medical Sciences, University of South Australia

Haemagglutination is a form of agglutination where antibodies bind to red blood cells. Red blood cells are both readily available and the results are readily observable using the naked eye. This video demonstrates the steps involved in a haemagglutination assay, interpreting the results and determining the titre.
