Question

Quizplus · Accepted Answer

Sensitivity reflects how few antigen or antibody molecules a test can detect, while specificity measures how selective an antibody is. Option A is incorrect because it describes specificity, not sensitivity. Option B describes cross-reactivity, which is unrelated to sensitivity or specificity. Option D is incorrect because sensitivity is an essential parameter for any serological test.
