Accuracy and precision of methods for theophylline measurement in physicians' offices.
We tested the accuracy and precision of five theophylline methods intended for use in physicians' offices. The Syntex AccuLevel, Ames Seralyzer, and 3M Diagnostics TheoFAST methods were less reproducible (CVs 6.3% to 9.2%) than the Abbott Vision and Kodak DT-60 (CVs 2.2% to 3.3%). Caffeine interfered with the Vision, Seralyzer, and AccuLevel methods, and theobromine interfered with the Vision, ...
متن کاملA physician's office-based digoxin assay (Seralyzer) evaluated for interference by endogenous digoxin-like immunoreactive factors.
A digoxin test for a physician's office based-chemistry analyzer (Ames Seralyzer) was evaluated for possible interference by digoxin-like immunoreactive factors (DLIF). Sera from patients likely to have high concentrations of DLIF (renal and hepatic patients, pregnant women, and neonates) as well as from normal patients and umbilical cord blood were analysed by the Seralyzer digoxin immunoassay...
متن کاملA unitized enzyme-labeled immunometric digoxin assay suitable for rapid testing.
An enzyme-labeled immunometric assay has been developed for measuring digoxin concentrations in serum or plasma. Unitized, compartmentalized reagents are used with an automated sample-processing instrument. The enzyme activity of the processed sample, which is directly proportional to the digoxin concentration, is measured by using a reagent strip and the Ames Seralyzer reflectance photometer. ...

We used dried blood spots successfully as alternative specimens for quantifyingconcentrationsof theophyllinein the circulation by a modified fluorescence polarization immunoassay (FPIA) with the Abbott TDx instrument. The method described is simple, rapid, and acceptably precise. More importantly, it can provide results comparable with those of the conventional serum assay. Results for 64 pairs...
متن کاملThe theophylline method of the Abbott "Vision" analyzer evaluated.
We evaluated the analytical performance of the Abbott "Vision" analyzer for theophylline measurement. The within-day precision (CV) was 1.8% and 3.1% at theophylline concentrations of 15.2 and 25.2 mg/L, respectively; between-day precision was 3.5% and 4.8% at 14.9 and 24.4 mg/L, respectively. Bilirubin (143 mg/L) and triglyceride (7.4 g/L) did not interfere, but hemoglobin caused lower values ...
