The of a test means the test can detect even very small concentrations of the antigen or antibody being analyzed, whereas the of a test focuses on the ability of a test to only detect the desired antigen or antibody without reacting with other unrelated substances.

SENSITIVITY

SPECIFICITY

Explanation:

Antigens refers to those particles that trigger the body to create an antibody. Antibodies on the other hand are part of the defence immune system of the body.

The tests used in detectection of antibodies and antigens help to us to get out some certain infections as well as other medical conditions.
