A simple, rapid and cheap radioimmunoassay for plasma digoxin.

ABSTRACT

A radioimmoassay for digoxin is described which uses commercially available reagents. Two assay procedures are used, one for batch assays, and another, which needs a 5 minute incubation only, for 'stat' assays. The methods are shown to be simple, rapid, precise and inexpensive and the batch procedure compared well with the Amerlex digoxin method for 63 patient samples.
