Answer:
- Similarities both are diffusion process
- wells are involved.
Radial Immunodiffusion (RID) Quantitative test technique quantitative radial immunodiffusion is based upon the reaction between an Ag, and a specific Ab during a diffusion period.
• Ag placed in a well diffuses into an agar containing the Ag (anti-IgG looking for serum IgG).
• The Ag-Ab interaction is manifested by well-defined ring of precipitation around the Ag well.
Explanation:
While Ouchterlony double diffusion (Immunodiffusion) Qualitative test It is based upon the simultaneous application of Ag and Ab in separate but adjacent wells of an agar plate.
• As the materials diffuse toward one another, ppt. lines form resulting from the Ag-Ab interactions.
• If multiple wells of Ag are positioned around an Ab well on the same plate, several patterns of reactivity may be observed.
