Origin: Formed within English, by compounding. Etymons: radio- comb. form², immunoassay n. at immuno- comb. form 2

Etymology: < radio- comb. form² + immunoassay n. at immuno- comb. form 2.

Medicine and Biology.

Any of various methods of detecting or measuring antigen or antibody using radiolabelled reagents; spec. a highly sensitive assay in which the unlabelled antigen in a test sample competes with radiolabelled antigen for binding to a specific antibody. Abbreviated RIA.
