Which of the Following is Most Associated with a Low

Question

Which of the following is most associated with a low plasma level of antibodies?
A) The "booster" response
B) The primary response
C) An autoimmune response
D) Anaphylaxis

Accepted Answer

The primary response is the first encounter with a pathogen and results in the production of low levels of antibodies. As such, a low plasma level of antibodies would be most associated with the primary response. The booster response refers to the production of an increased amount of antibodies upon re-exposure to a pathogen, which would not result in a low level of antibodies. Autoimmune responses and anaphylaxis are immune system disorders that are not directly related to plasma levels of antibodies.
