Concept explainers
To define: The terms sensitivity and specificity relating to immunological testing.
Introduction: Immunologic tests employ an artificial antigen or antibody to detect the presence of an antibody or antigen of the pathogen in the suspected samples. Immunological tests are highly sensitive, and they involve specific interactions between antigens and antibodies.
Explanation of Solution
The ability of the test to exactly identify the true positive rate of the disease is termed as sensitivity. It is a measurement of how good a test demonstrates whether the suspected sample has the disease or not.
The ability of the test to exactly identify the true negative rate of the disease is termed as specificity. It is the proportion of healthy individuals who were known not to have the disease and provide negative test results.
