We describe a radioimmunoassay for the routine determination of digoxin in urine
employing readily available commercial reagents. The standard curve was found to exhibit …

The concentrations of digoxin in plasma and urine samples obtained from three healthy
male volunteers, who received 1.2 mg of labeled digoxin perorally and intravenously, were …

Abstract Evaluation of commercial kits (3H and 125I digoxin) for the radioimmunoassay of
digoxin showed that different normal plasma samples yielded significantly different standard …

We evaluated four commercial radioimmunoassay kits for digoxin. We assayed a standard
plasma containing digoxin, 2.0 microgram/L, and samples from patients receiving digoxin …

A specific method for the quantitation of digoxin in serum has been developed and applied
to determination of drug concentrations in serum from digitalized patients. One ml of the …

This method for assaying digoxin in serum with improved specificity combines small-column
extraction of serum," high-performance" liquid chromatography, and RIA of the eluted …

A rapid, precise and accurate radioimmunoassay for the measurement of digoxin has been
developed. The method employs a column of immobilized antibody which acts as both …

Six commercially available kits for radioimmunoassay of digoxin were compared. When
serum from patients with chronic renal failure on maintenance digoxin therapy was …

A micro-radioimmunoassay of 125I-labeled digoxin is described in which 10-mul rather than
50-mul aliquots of sera are required. The method is a modification of a simplified, rapid, and …

Six commercial radioimmunoassay kits, employing iodinated tracer, for the analysis of serum
or plasma digoxin levels were evaluated. The adequacy of the literature supplied with the …
