Current status of fluorescent immunoassays

In 1941 fluorescent compounds were first introduced as immunochemical labels in assay systems. Several forms of quantitative fluorescent immunoassay, which represent a major alternative to radioimmunoassay and enzyme immunoassay, have been developed and are now widely used in many clinical laboratories. This paper discusses these forms and procedures and their advantages over radioimmunoassay and enzyme immunoassay.
