Immunodiffusion
MeSHD005779

Immunodiffusion is a diagnostic test which involves diffusion through a substance such as agar[1] which is generally soft gel agar (2%) or agarose (2%), used for the detection of antibodies or antigen.

The commonly known types are:

  1. Single diffusion in one dimension (Oudin procedure)
  2. Double diffusion in one dimension (Oakley Fulthorpe procedure)
  3. Single diffusion in two dimensions (radial immunodiffusion or Mancini method)[2]
  4. Double diffusion in two dimensions (Ouchterlony double immunodiffusion)[3]
