3D Body Scanning provides access to a greater breadth and depth of anthropometric data for industry applications and scientific research than at any other point in history. However, while the potential of this technology for revolutionising industrial and scientific practices has been established, little exists addressing its appropriateness in terms of reliability within recognised allowable e...
In connection with "maximum allowable concentrations in biological materials ", I should like to express some views on the value of measuring mercury and cadmium concentrations in urine. These remarks are based on findings in human subjects and in experimental animals. Mercury which is absorbed into the body is largely excreted in the urine. From this. aspect, therefore, determination of the ur...
Background Phlebotomy for the purpose of blood analysis is often performed at remote locations, and samples are usually temporarily stored before transport to a central laboratory for analysis. The circumstances during storage and shipment may not meet the necessary requirements. If analysed anyway, false results may be generated. We therefore examined the influence of precentrifugation time an...
Diabetes mellitus is a major global health problem. Pathology testing for hemoglobin A1c (HbA1c), lipids, and urine albumin/creatinine ratio (ACR) has an important role in the management of diabetes patients. Each of these markers can be performed by point-of-care testing (POCT). This article focuses on setting analytical goals (quality specifications) for the imprecision, bias, and total allow...
BACKGROUND Routine repeat testing of critical laboratory values is very common these days to increase their accuracy and to avoid reporting false or infeasible results. We figure that repeat testing of critical laboratory values has any benefits or not. METHODS We examined 2233 repeated critical laboratory values in 13 different hematology and chemistry tests including: hemoglobin, white bloo...
BACKGROUND The urinary iodine micromethod (UIMM) is a modification of the conventional method and its performance needs evaluation. METHODS UIMM performance was evaluated using the method validation and 2008 Iodine Deficiency Disorders survey data obtained from four urinary iodine (UI) laboratories. Method acceptability tests and Sigma quality metrics were determined using total allowable err...
OBJECTIVES Point of care testing (POCT) contributes to diagnosis and monitoring with fast testing time and easily performed assays. We evaluated the Abaxis Piccolo Xpress point of care chemistry analyzer using the Liver Panel Plus discs for our pediatric patient population at Texas Children's Hospital. DESIGN AND METHODS Analytical performance was evaluated for precision and linearity using q...
background and objective: the reliability and validity of monitors for self-monitoring of blood glucose are debated. we evaluated the analytical performance of accu-check active (boehringer mannheim, roche) which is one of the most commonly used monitors in iran. material and methods: we compared the monitor readings with the reference values by percentage of values within certain intervals of...
