Background
- Haemagglutination is a specific form of agglutination.
- Red blood cells serve as particulate antigens in this assay.
- Antibodies can cross-link these cells, forming visible complexes.
- The results are easily observable with the naked eye.
Purpose of Study
- To determine the reactivity of serum using a haemagglutinin assay.
- To demonstrate the steps involved in conducting the assay.
- To interpret the results effectively.
Methods Used

- Visual confirmation of antibody presence.
Conclusions
- Haemagglutination assays are effective for serum analysis.
- Results can be easily observed and interpreted.
- This method is valuable for immunological studies.
What is haemagglutination?
Haemagglutination is the agglutination of red blood cells due to the binding of antibodies.
Why are red blood cells used in this assay?
Red blood cells are readily available and their agglutination can be easily observed.
What does the titre indicate?
The titre indicates the concentration of antibodies present in the serum.
How are results interpreted?
Results are interpreted based on the presence or absence of agglutination patterns.
Is this method applicable to other antigens?
Yes, while this assay focuses on red blood cells, it can be adapted for other particulate antigens.
What are the advantages of this assay?
The assay is straightforward, cost-effective, and provides quick results.
