TYPES OF AGGLUTINATION REACTIONS

Question 1

Ideal for detecting UNKNOWN ANTIBODIES in a patient’s serum

Answer 1

DIRECT AGGLUTINATION

Question 2

RBCs are used as indicators

Answer 2

HEMAGGLUTINATION

Question 3

Semiquantitative analysis OF DIRECT AGGLUTINATION can be made through _______________?

Answer 3

Antibody titration

Question 4

What are the examples of Agglutination tests?

Answer 4

Widal test and Blood typing

Question 5

Detect antibodies for diagnosing typhoid fever

Answer 5

Widal Test

Question 6

This uses a test kit containing antigens to salmonella bacteria

Answer 6

Widal Test

Question 7

Direct agglutination, however what we are looking for is antigen (RBCin the indicator particle that will determine the blood type

Answer 7

Blood Typing

Question 8

In blood typing, what are we looking for?

Answer 8

Antigen

Question 9

Involves the conjugation of antigens with carrier particles (latex, gelatin, RBCs) that Detects UNKNOWN ANTIBODIES in samples.

Answer 9

INDIRECT/PASSIVE AGGLUTINATION

Question 10

Used for detecting mostly IgM antibodies for the following infections:
o Group A Streptococcus (ASO Determination and Titer)
o Rotavirus
o CMV (Cytomegalovirus)

Answer 10

INDIRECT/PASSIVE AGGLUTINATION

Question 11

Antibodies are conjugated to particles through adsorption that Detects UNKNOWN ANTIGENS in samples

Answer 11

REVERSE PASSIVE AGGLUTINATION

Question 12

Antigens are stealing antigen binding sites from the antibodies

Answer 12

COMPETITIVE IMMUNOASSAY

Question 13

what is the end result (positive) of competitive immunoassay?

Answer 13

absence of agglutination

Question 14

Where can we use agglutination inhibition?

Answer 14

Drugs of abuse such as heroin and cocaine

Question 15

Viral particle that binds to the surface of RBC

Answer 15

Spontaneous Agglutination
