The effect of renal function and digoxin use in adult patients on interference from digoxin-like immunoreactive substances (DLIS) with three digoxin immunoassays was studied. Hospital patients entered into the study were categorized into the following groups according to renal function: group I (serum creatinine less than 1.5 mg/dL), group II (serum creatinine 1.5-2.5 mg/dL), group III (serum creatinine greater than 2.5 mg/dL, not on hemodialysis), and group IV (serum creatinine greater than 2.5 mg/dL, on maintenance hemodialysis). Medical records were reviewed to determine whether or not patients were receiving digoxin. Excess sera for analysis of serum digoxin concentrations (SDCs) was collected from routine laboratory tests. Serum samples were assayed singly by fluorescence polarization immunoassay (FPIA, Digoxin I, Abbott), radioimmunoassay (RIA, Micromedic), and affinity-column-mediated immunoassay (ACMIA, aca, E.I. du Pont). Correlation of SDCs obtained by RIA and ACMIA with FPIA results was determined using linear-regression analysis. A total of 177 patients met the study criteria; 98 were receiving digoxin. In patients on digoxin, SDCs by RIA were significantly higher than those obtained by FPIA in group II and III patients. SDCs obtained by ACMIA correlated well with and were not significantly different from those obtained by FPIA in any of the patient groups. Maximum differences and mean absolute differences in SDCs obtained by RIA were greater than those for ACMIA when compared with FPIA values in all patient groups. Over 40% of patients with renal dysfunction not on digoxin had false-positive SDCs by RIA; the highest of these values was seen in groups II and III.(ABSTRACT TRUNCATED AT 250 WORDS)
