Cross reactivity of digitoxin and spironolactone in two radioimmunoassays for serum digoxin.

Abstract:

:We measured the cross reactivity of two medications--digitoxin and spironolactone--in two digoxin radioimmunoassay (liquid and solid-phase) kit procedures. Both tests showed similar average percentages of cross reactivity with digitoxin (7.2 and 8.9% for intravenous, and 11.9 and 10.9% for oral administration), but no cross reactivity with spironolactone or its metabolites after equal intravenous or oral doses.
