Examining techniques for radioimmunoassay of digoxin in urine, we found that the apparent concentration of digoxin is affected by endogenous substances, independent of the concentration of digoxin itself. We describe a modification of the Becton Dickinson solid-phase RIA that makes it more nearly accurate and more easily performed, and obviates the endogenous interference. Digoxin concentrations from 5.0 to at least 1000 micrograms/L can be measured.
在研究尿中地高辛放射免疫测定的检测技术时，我们发现地高辛的表观浓度受内源性物质影响，与地高辛本身的浓度无关。我们描述了一种对贝克顿·迪金森固相放射免疫分析法的改进方法，该方法使其更准确、更易于操作，并消除了内源性干扰。地高辛浓度在5.0至至少1000微克/升之间均可测定。
