Abstract
Substituted hydantoin drugs (for example phenytoin) and tricyclic antidepressant drugs (for example nortriptyline) are assayed by mixing them with a fluorescent labelled compound and antibodies, and measuring the fluorescence of the mixture. The assay does not necessitate any separation step and may be effected by continuous-flow techniques.
