title: Rapid acyclovir radioimmunoassay, using charcoal adsorption.
abstract: Charcoal adsorption of unbound acyclovir rather than ammonium sulfate precipitation of bound acyclovir to facilitate the separation of bound antigen from free antigen gave rise to a radioimmunoassay which was quicker yet still as sensitive and accurate as that previously used.
