Radioimmunoassay of digoxin: aspecific interferences of human plasma

L. Padeletti

Research output: Chapter in Book/Report/Conference proceedingChapter


A radioimmunoassay for determination of digoxin in human plasma is described. After extraction of plasma with ethyl acetate, the radioimmunoassay is performed using an antiserum to digoxin BSA and charcoal. Precision, accuracy, sensitivity and specificity were evaluated. The comparison of two methods based on the direct measurement of digoxin without extraction showed the presence of aspecific interferences coming from human plasma when plasma samples are not extracted.
