D- Agar-Gel Immunodiffusions (AGID)

The agar-gel immunodiffusion (AGID), also referred to as an agar gel precipitin

(AGP) test, involves the diffusion of virus and antibody through an agar (gelatin-

like substance), which will form a line of identity where the antigen-antibody

complexes form.

E- Latex Particle Agglutination

• Perhaps the simplest of all immunoassays is the agglutination by antigen of small

latex beads previously coated with antiviral antibody.

• The test can be read by eye within minutes.

• Not surprisingly, diagnostic kits based on this method have become popular with

small laboratories and with medical practitioners.
