Abstract
Novel reagents for the detection by immunoassay of drugs in body fluids, their preparation and use are disclosed. The reagents of the present invention correspond to the formula EQU P--[A--D].sub.n where: PA1 D is a drug derivative suitably selective for the determination of the presence of the target drug or drug metabolite, PA1 A is an activating linker-spacer group having an N-hydroxysuccinimide or isothiocyanate derived linking moiety, PA1 P is a poly(amino acid) or polymer capable of covalently bonding with A, and PA1 n is less than l.
