Analytical Performance Evaluation of EMIT#{174} II Monoclonal Amphetamine/ Methamphetamine Assay: More Specificitythan EMIT#{174} d.a.u.TMMonoclonal Amphetamine/Methamphetamine Assay
We evaluated a new EMIT#{174} II monoclonal amphetamine! methamphetamine assay for screening human urine by comparing itwith the EMIT#{174} d.a.u. monoclonal amphetamine/methamphetamine assay and a fluorescence polarization assay. The EMIT II assay has a cutoff of 1 mg!L d-methamphetamine. The EMIT II and EMIT d.a.u. assays were run on a BM/Hitachi 704 analyzer; for the fluorescence polarizatio...
متن کاملFailure of current laboratory protocols to detect lot-to-lot reagent differences: findings and possible solutions.
BACKGROUND Maintaining consistency of results over time is a challenge in laboratory medicine. Lot-to-lot reagent changes are a major threat to consistency of results. METHODS For the period October 2007 through July 2012, we reviewed lot validation data for each new lot of insulin-like growth factor 1 (IGF-1) reagents (Siemens Healthcare Diagnostics) at Mayo Clinic, Rochester, MN, and the Un...
متن کاملBuflomedil interference with the monoclonal EMIT d.a.u. amphetamine/methamphetamine immunoassay.
The interference of buflomedil with the monoclonal and polyclonal EMIT d.a.u. amphetamine immunoassays was investigated. Urine samples collected from 20 patients taking 600 mg of buflomedil daily gave false positive results with the monoclonal EMIT d.a.u. assay, as did urine specimens collected 2 hours after the first oral dose of buflomedil. Conversely, no false positive results occurred with ...
متن کاملHow to Use MRP in Continuous Production Industries When Order Type is Lot for Lot
The Materials Requirements Planning (MRP) method that is applied in production planning and management has some weaknesses. One of its weaknesses is that the time in MRP method is discrete, and is considered as time period. Hence we are not able to order our requirements at irregular time moments or periods. In this paper, a new form of MRP is introduced that is named Continuous Materials Requi...
متن کاملUse of the Reflotron system for cholesterol assay in capillary blood, venous blood, and serum--evaluation of accuracy and lot-to-lot reagent comparability.
Since its recalibration in 1987, the Reflotron "dry-chemistry" cholesterol method can produce accurate results. Here we report how cholesterol concentrations in venous blood, plasma, and serum determined with Reflotron compare with values determined for fingerstick samples. When no EDTA is used in the latter, accurate results may meet the WHO/CDC criterion of a maximum bias less than or equal t...
