Abstract
Precision and accuracy of the enzyme-linked immunosorbent assay (Enzymun-Teste ®) were examined in determination of serum digoxin level. Coefficients of variation for analyses of the 3 levels of digoxin were less than 10% in both of within-run and between-run. Results of the present method was compared with those of radioimmunoassay (RIA) and homogeneous enzyme immunoassay (EMIT ®) in determination of serum digoxin levels in the patients with cardiac failure. It was found that correlations between the results of the present method and those of the others were fairly good.
