Honey as a candidate reference material for trace elements.
The feasibility of producing and certifying new certified reference materials (CRMs) for trace elements in honey was investigated. Preliminary steps for preparation of candidate materials are performed at the Institute for Reference Materials and Measurements, Joint Research Centre of the European Commission (EC-JRC-IRMM). Two different types of honey, Acacia and Eucalyptus, were tested for det...
متن کاملCharacterisation of trace elements and methylmercury in an estuarine sediment reference material, IAEA-405.
An estuarine sediment sample, IAEA-405, was recently characterised for trace elements and methylmercury (MeHg) for ultimate use as a marine reference material. The reference values were calculated using data sets from 120 laboratories that participated in a world-wide intercomparison exercise. The data evaluation is highlighted, and includes comparisons of different analytical methods, as well ...
متن کاملReference values for methemoglobin concentrations in children
OBJECTIVE The aim of this work was to establish reference values for methemoglobin levels in 6 to 10-year-old children. METHODS Methemoglobin concentrations were studied in clinically healthy children. The method for methemoglobin measurement used, neither uses highly toxic chemical compounds nor expensive enzymatic methods, thus it is feasible in the laboratory routine. RESULTS The results...
متن کاملIgG subclass concentrations in certified reference material 470 and reference values for children and adults determined with the binding site reagents.
BACKGROUND There is currently no international reference preparation for IgG subclass (IgGSc) quantification. This situation has led to calibration differences among assays and a variety of reference interval values with consequential difficulties in comparing results. We therefore evaluated IgGSc concentrations in Certified Reference Material 470 (CRM 470). METHODS Pure, polyclonal IgG1, -2,...
متن کاملReference Values for Serum Total Cholesterol Concentrations Using Percentile Regression Model: A Population Study in Mashhad
Background and Purpose: Serum total cholesterol (TC) concentrations are affected by several factors including ethnicity, diet, geographic, and environmental determinants, and are related to another disease, including hypothyroidism, and renal and liver disease. It is associated with an increased risk of cardiovascular disease, particularly if associated with high levels of serum low-density lip...
