Immunoassay

Definition

An assay using antigen–antibody recognition under specified conditions. Fluorescent responses can also decrease through interactions described as quenching. A signal change is interpreted within the validated assay. It does not by itself establish a material’s identity, concentration or source.

Context
Assay mechanisms

For example, a target-binding response must be interpreted with the assay’s controls and specificity rather than treated as proof of a donor or activity.
