agglutination Flashcards
a process by which a particulate antigens such as cells aggregate to form a large complex when a specific antigen is present
a. precipitation
b. electrophoresis
c. agglutination
d. passive immunodiffusion
agglutination
the first reaction involves in Ag and Ab combination through single antigenic determinant on the particle surface
a. affinity
b. avidity
c. sensitization phase
d. lattice formation
sensitization phase
- 1st reaction
lattice formation
- sum of interactions between Ab and Ag
antigens are found naturally on a particle
a. direct agglutination
b. passive agglutination
c. reverse passive
d. coagglutnation
direct agglutination
- antigen is NATURALLY on a particle
- detection of antibody/ agglutination may occur if there is present of Antibody
antigen is attached to a carrier particle
a. direct agglutination
b. passive agglutination
c. reverse passive
d. coagglutnation
passive agglutination/ indirect
- antigen is ATTACHED to a carrier particle
- detection of antibody/ agglutination may occur if there is present of Antibody
antibody is attached to a particle
a. direct agglutination
b. passive agglutination
c. reverse passive
d. coagglutnation
reverse agglutination
- ANTIBODY IS ATTACHED to a particle
- dteection of Antigen
- to detect microbial agents
- CRP and Haptoglobulin
what bacteria frequently used coagglutination
a. staphylococcus aureus
b. streptococcus pyogenes
c. escherichia coli
d. klebsiella
coagglutination
- use bacteria as the inert particle
- Staphylococcus aureus
this type of agglutination has result that is lack of agglutination indicates positive reaction
a. direct agglutination
b. passive agglutination
c. reverse passive
d. agglutination inhibition
agglutination inhibition
- lack of agglutination indicates positive reaction
- involves HAPTENS
- hcg test
