AGGLUTINATION AND PRECIPITATION REACTION

This uses the electrophoresis of serum followed by diffusion of antibodies from the wells

• Immunoelectrophoresis

• Agglutination Inhibition

• Radial Immunodiffusion

• Immunofixation electrophoresis

Lack of agglutination is a positive test, indicating the presence of patient antigen

• Immunoelectrophoresis

• Agglutination Inhibition

• Radial Immunodiffusion

• Immunofixation electrophoresis

This is used to detect antigen that moves out of the gel containing antibody added to it

• Immunofixation electrophoresis

• Radial Immunodiffusion

• Direct Agglutination

• Agglutination Inhibition

This is used for the detection of over or under production of antibodies

• Immunofixation electrophoresis

• Agglutination Inhibition

• Immunoelectrophoresis

• Direct Agglutination

This uses lines of precipitate formed to indicate the relationship of antigens

• Ouchterlony Double Diffusion

• Direct Agglutination

• Immunofixation electrophoresis

• Radial Immunodiffusion

When the amount of antigen overwhelms the number of antibody combining sites present, it is said to be in what part of the precipitation curve?

• prozone

• postzone

• prezone

• zone of equivalence

When the amount of antibody overwhelms the number of antigen combining sites present, it is said to be in what part of the precipitation curve?

• prozone

• postzone

• prezone

• zone of equivalence

The particle-counting immunoassay instrumentation technique uses the principle of?

• Nephelometry

• Turbidimetry

• FSC

• NOTC

Agglutination indicates the presence of patient antigen

• Reverse Passive

• Hemagglutination inhibition

• Agglutination Inhibition

• Direct Agglutination

Particles are coated with antigens not normally found on their surfaces

• Agglutination Inhibition

• Indirect or Passive Agglutination

• Direct Agglutination

• Hemagglutination Inhibition
