Level Analysis

Abstract Although the overall quality assurance concepts and goals for pesticide formulation analysis are similar to those required of an environmental or trace level analysis laboratory, some important distinctions exist, particularly for quality control. Generally, target levels (label values) are known and pesticide identification can be assumed, thus minimizing the need for verification of pesticide identity and for detailed confirmation of quantitative results reasonably close to the label value. Exceptions are cross-contaminant screening and by-product analysis. Quality control efforts in the formulation laboratory are concentrated on those samples falling outside the established acceptance criteria. The use of official (AOAC/Collaborative International Pesticides Analytical Council (CIPAC)) methodology, replicate determinations, second analyst confirmation, and alternative methodology (if necessary) is stressed. Specific attention must also be paid to the quality and preparation of analytical reference standards.

Equipment Performance

Activimeters (or dose calibrators) are essential instruments to verify activity of radiopharmaceutical after production and also before the dose administration in humans or animals for molecular imaging. The efficiency and safety measurements depend on, beside other factors, constancy tests and quality assurance. Thereby, the aim of this work was to perform constancy tests and quality assurance in the activimeters of the UPPR/CDTN, based on the CNEN-NN 3.05 Brazilian standard and the manufacturer's manual. Physical inspection, auto zero, background check, camera voltage, data check and constancy test were done. In addition, accuracy and precision tests were performed using a set of standard certified radioactive sources (57Co, 133Ba and 137Cs), according to the CNEN NN 3.05 Brazilian standard. Linearity test was also performed to evaluate the response of the equipment in over the entire range of activities used in routine. The equipments are periodically submitted to the quality control tests and the results were compared. After performing the proposed tests it is possible to conclude that activimeters are in accordance with the requirements of the CNEN standard and manufacturer´s manual. A quality control checklist was prepared to guide users and to record the results of quality assurance testing to monitor the equipment performance. This initiative is part of the quality assurance program implemented at UPPR.

Keywords Quality Assurance

Quality assurance and quality control is the foundation of any diagnostic test. The two laboratories in the United States that use HPLC to quantitate endophyte toxins in tall fescue (Festuca arundinacea) and perennial ryegrass (Lolium perenne) are Oregon State University (OSU) and University of Missouri (MU). Japan, the major importer of grass straw has six new laboratories that will test agricultural imports for endophyte toxins. A quality assurance program was set up between the Japanese Ministry of Agriculture and the State of Oregon. The latter includes both OSU and the MU. All units are using an accurate crystalline standard and have exchanged "check" samples among themselves. To date OSU and MU have values that differ by 10%. OSU has identified a contaminating and coeluting peak as the cause of the differences. Both laboratories are changing to a Gemini column to rectify the differences. Japanese laboratories are in the process of evaluating their split check samples. Keywords: quality assurance, quality control, endophyte, tall fescue, perennial ryegrass

Structural Concrete

The variability associated with the production, construction, and testing of structural and paving concrete is discussed. Data from more than 900 projects constructed from 1992 through 1999 representing more than 25,000 lots were evaluated. The data were collected from the Louisiana Department of Transportation and Development’s (DOTD’s) computerized Material Test Data Reporting System. The analysis indicated that ( a) overall price reductions were less than 0.2% for structural concrete and about 0.5% for paving concrete, ( b) the thickness of concrete cores is the major contributor to the overall reduction in the price of paving concrete, ( c) there was good control in the production and testing of structural concrete, and ( d) there was an increase in the nonuniformity of paving concrete acceptance criteria. Recommendations include a need to maintain better control of the variability of paving concrete through the application of control charts or unknown variability in the specification types and a need for continued evaluation for monitoring the overall quality control and quality assurance program of the DOTD.

The design, construction, operation, maintenance, and decommissioning and decontamination of nuclear infrastructure particularly nuclear power plants licensed in the US by the US Nuclear Regulatory Commission (NRC) or operated by the US Department of Energy (DOE) or the US Department of Defense (DOD) must be executed under a rigorous and documented quality assurance program that provides adequate quality control and oversight. Those codes, standards, and orders regulate, document and prescribe the essentials for quality assurance (QA) and quality control (QC) that frequently impact nuclear facilities operated in the US are reviewed and compared.

Abstract A special standardization and quality assurance program, similar to that created for the Lipid Research Clinics Program (LRC), was developed for the American Health Foundation Laboratory by the Centers for Disease Control (CDC) to assure the quality of lipid measurements in the U.S. Air Force Health Evaluation and Risk Tabulation (HEART) Program. This study was designed to test the feasibility of reducing the incidence of heart disease in active-duty U.S. Air Force personnel through life-study intervention. During the 18-month study, CDC provided serum calibrators and reference materials for internal control and an external surveillance program for measurements of total cholesterol (TC) and high-density-lipoprotein cholesterol (HDLC). The Laboratory, using an automated enzymic method to measure cholesterol, achieved an overall goal for accuracy of less than 2% error (av systematic error, -30.6 mg/L) for TC, as measured on nine reference pools for which values were assigned by CDC. The average bias of measurements of HDLC with heparin-manganese to separate the lipoproteins in five CDC reference pools was -4.6 mg/L. Bias was estimated relative to the values assigned to the reference materials by the CDC reference methods for TC and HDLC. The average CV for TC was 0.89%, for HDLC 2.66%. Accuracy of cholesterol measurements can be assured over time with a standardization and quality-assurance program that incorporates accurately labeled reference materials for calibration, internal quality control, and external surveillance.
