Hemagglutination inhibition assay (HAI)for flu vaccines - Humoral Immunity
Titration of antibodies against influenza vaccine (HIA):
Texcell offers the titration of antibodies against influenza vaccine in patient samples from clinical trials. As recommended by WHO, we perform titration using a haemagglutination inhibition assay (HIA).
Depending on the WHO's annual recommendations, we offer different strains in collaboration with national flu reference centres.
e.g.: in the winter of 2005 for the northern hemisphere, the vaccines contained the following strains:
- A/New Caledonia/20/99(H1N1)-like virus
- A/California/7/2004(H3N2)-like virus a
- B/Shanghai/361/2002-like virus b
