We assayed serum gentamicin and tobramycin specimens by the enzyme multiplied immunoassay technique (Syva EMIT) and the fluorescence polarization immunoassay (Abbott TDx). When interassay and intraassay control samples were evaluated, both methods gave an overall coefficient of variation of less than +/- 10%. Using patient serum samples, we obtained excellent correlation with both methods in th...

A new fluorescence polarization (FP) immunoassay was developed for the COBAS INTEGRA to quantitate lidocaine in serum and sodium heparin derived plasma. The COBAS INTEGRA, a random and continuous access clinical analyzer, performs the new lidocaine assay at a throughput of 300 tests per hour. Comparison studies with the Abbott TDx Lidocaine assay yielded a correlation coefficient of 0.99 and a ...

Large numbers of specimens (5000-18,000) were screened for amphetamines, barbiturates, cocaine, marijuana, opiates, and phencyclidine by RIA (Roche), Emit II (Syva), and a new immunoassay, CEDIA (cloned enzyme donor immunoassay, Microgenics). All immunoassays performed equivalently for cocaine, opiates, and phencyclidine. All immunoassays detected the same amphetamine/methamphetamine-positive s...

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, ...

The Tsaoling Landslide in Taiwan has captured attentions of researchers worldwide due to its frequent catastrophic failure and distinctive features. Thanks to the launch of TerraSAR-X/TanDEM-X (TSX/TDX) constellation, retrieval of global DEM with high spatial resolution and accuracy becomes possible, which is extremely useful for the study of natural hazards (e.g., landslides) globally. We atte...

there are several varieties of edge detection method. edge detection and edge enhancement techniques play an essential role in interpreting potential field data. some of common methods are: tilt angle filter (ta), total horizontal derivative of tilt angle filter (thdt), theta filter, tdx filter, hyperbolic tilt angle (hta). these filters maximum values are when facing with the edge of an anomal...

Cyclosporine is used in the prevention of allograft rejection. Owing to its narrow therapeutic index, regular monitoring of the whole blood levels of cyclosporine is required. We observed that immunoassays measured significantly higher cyclosporine levels than did high-performance liquid chromatography (HPLC) over time after transplantation. As cyclosporine metabolites crossreact even with immu...
