Antiserum specificity for digoxin was demonstrated by means of three tests: cross-reactivities test, dilutions test and thin-layer chromatography test. The cross-reactivities test examined quantitatively the cross-reactivities with specific compounds and provided an explanation for the basis of the dilutions test. The dilutions test was used to demonstrate the suitability or unsuitability of the antiserum for use in the radioimmunoassay of digoxin in a crude biological sample. The tlc test examined for antiserum cross-reactivity with digoxin and related compounds in a crude extract.
