Chapter 17, Problem 8MC
Summary Introduction
Introduction:
Serology is a method which is used to analyze the blood for the presence of a specific antibody and antigens. There is a wide-range of serological tests available to recognize the antigens or antibodies in the blood. Using the tagged or labelled antibody to identify an antigen is an altered form of serological testing method, for example, ELISA, fluorescent antibody tests, and immune blotting tests.

To diagnosis, we used a procedure known as a "sandwich ELISA" (Enzyme-Linked Immunosorbent Assay).
1.In the "ELISA sandwich," what is the "meat"?
2.Both patients A and B had positive results. Why are these two patients' outcomes so different?
3.What is one potential cause of an ELISA false negative result? What is one potential cause of an ELISA false positive result? What is another example of how an ELISA assay should be used?
If you were using the ELISA to look for the presence of antibodies and the sample gave a negative result, does this mean that there were no antibodies present? Explain.
Describe the following antigen antibody reactions in serology:
Mechanism
Function in serology
Example of method
a) Precipitation
b) Agglutination
c) Neutralizing
d) Complement fixation

Why? I understand that secondary antibody aids in the detection, sorting or purification of target antigens by binding to the primary antibody which directly binds to the target antigen. However, I don't undrstand why there are only two or three secondary antibodies available in the laboratory. Glad if the expert would advise.arrow_forward
