کنترول کیفی آزمایشهای سرولوژی بنا م خداوند بخشنده مهربان 1. Labeled Immunoassay Enzyme Linked Immuno Sorben Assay ( ELISA ) Radio Immuno Assay ( RIA ) Immuno Flurescent Antibody Technique ( IFAT ) Electrochemilominsance ( ECL ) 2.Non Labeled Immunoassay. Agglutination tests Precipitation tests Fluccolation tests Agglutination Reactions Direct agglutination Passive agglutination Agglutination inhibition Ab + particulate Ag Agglutination (clumping) Direct agglutination Example # 2 – Using bacteria (Ag) looking for Ab in serum. Indirect or Passive agglutination Results when inert particles are coated with soluble Ags which may react with Ab. Particles include latex, rbc’s, charcoal, etc. Example – Ag attached to latex particle (known) + serum looking for (unknown) Ab. If Ab present, you get visible agglutination. Reverse passive agglutination Involves the adherence of Ab to inert particles which can then be used to detect the presence of Ag. Example – latex particle coated with Ab (known) + serum looking for (unknown) Ag. If Ag present, then you get visible agglutination.
