title: [Fluoroimmunometric method of determining digitoxin].
abstract: Digitoxin at concentrations up to 5 x 10(-10) M (therapeutic concentrations are 2 x 10(-8) M) can be reliable measured by a fluoroimmunometric method with coproporphyrin as a tracer. The use of nylon filters with immobilized digitoxin to remove an excess of labelled antibodies increases reliability and reduces the time of measurements, and thus simplifies the assay.
