Direct agglutination occurs when antibodies and antigens are found naturally on a particle
True
False
Are the most often consideration when red blood cells are used as the carrier particle
Rheumatoid Factor
Heterophile antigen
Heterophile antibody
Monoclonal antibody
The reaction where the red blood cells are the indicator particles
Hemagglutination inhibition
Agglutination inhibition
Reverse passive agglutination
Titer
These particles are inexpensive, stable and are not subject to cross-reactivity with other antibodies
Erythrocytes
Charcoal
Silicates
Latex
The use of semi-synthetic beads or particles provides the advantage of consistency, uniformity and stablity
True
False
If the sample has no free hapten, the reagent antibody is able to combine with the ___ and produce a visible agglutination
Carrier particles
Indicator particles
Silicate particles
Erythrocytes particles
Systems using bacteria as the inert particles to which antibody is attached is called Coagglutination
True
False
This is a technique that detects non-agglutinating antibody by means of coupling with a second antibody also called Indirect Coomb's test
True
False
It is used to demonstrate in vivo attachment of antibody or complement to an individual's red blood cells.
Direct antihuman Test
Direct antiglobulin test
Indirect antiglobulin test
Widal test
Agglutination is the visible aggregation of particles caused by combination with two specific antibody
True
False
Sensitization step involves antigen-antibody combination through single ___ determinants on the particle surface.
Antibody
Affinity
Avidity
Antigenic
Passive agglutination employs particles which are coated with antigens not normally found on their surfaces
True
False
Agglutination inhibition reactions are based on the ___ between particulate and soluble antigens for limited antibody-combining sites.
Cooperation
Competition
Combination
Coagulation
Heterophile antibody and rheumatoid factors are two interfering antibodies that may produce a false-positive result.
True
False
Coomb's test is the most widely used procedure in blood banking
True
False
This type of testing is used to detect antibodies to certain viruses such as rubella, mumps, measles, herpes virus and adenovirus
Hemagglutination inhibition
Agglutination inhibition
Reverse passive agglutination
Indirect agglutination
The use of ___ has greatly cut down on cross-reactivity, but there i still a possibility of interference
Monoclonal antigens

Quality Control and Quality Assurance must standardize method of reading, incubation time, concentration of antigen temperature and diluent
True
False
This protein naturally absorbs the FC portion of antibody molecules which is found in staphylococcus aureus
Protein
Protein A
Titer
Globulin
Antigenics that produce such reaction are often called Agglutinins which involves sensitization followed by lattice formation
True
False
