Quizplus · Accepted Answer

Seroconversion refers to the development of detectable antibodies in response to an infection or vaccination. In Table 18.1, Patient A and Patient B both show an increase in antibody titer over time, indicating the development of antibodies and therefore seroconversion. Patient C has consistently low or undetectable antibody titer, suggesting no seroconversion. Patient D has a steady but low antibody titer, indicating possible prior exposure or vaccination but not seroconversion during these observations. Therefore, the best choice is A) Patient A and B) Patient B.
