Four commercial products for urine glucose determination were evaluated and compared with a quantitative hexokinase procedure. We examined precision, sensitivity, and analytical recovery of glucose from glucose-supplemented urine samples and comparison of methods, using patients' samples. Only "Chemstrip uG" (Bio-Dynamics Inc.) could differentiate between 0.3 g/L (upper limit of normal) and 0.6...

Professional societies have encouraged primary care providers to conduct spirometry testing for the detection of chronic obstructive pulmonary disease (COPD). In spite of this effort, the success rate is unacceptably low. Simple flow-sensing spirometers have technical flaws that can cause misreadings, and they are rarely checked for accuracy. When spirometry is performed by an experienced tech...

©2001 When I was young, I dreamed of being a writer, not a technologist. But, luck would have it otherwise. For the past twenty years, I have been intimately involved in the application of technology to marketing. Or, to put it a bit differently, I have been intimately involved in the application of technology to help companies understand their customer relationships, and as a result, more effe...

glucose 500 mg/L, acetoacetate 80 mgfL, bilirubin8 mg/L, hemoglobin 0.4mg/L, nitrite1 mg/L, and ascorbic acid 100 mgfL. The testsforproteinand ketones were more sensitive than the manufacLurer claims, throughout the range of concentrations studied, but for other analytes the expected results were obtamed. Abnormal urines submitted for unnalysis were collected, randomized, and analyzed with N-Mu...

The use of noninvasive ultrasound examinations can potentially result in significant anxiety in the pediatric population. The purpose of this study was to assess the influence of music during pediatric ultrasound examinations to reduce anxiety measured by heart rate. A total of 44 patients were recruited; 21 controls and 23 experimental. Each participant was randomized to either music or no mus...

A total of 730 Enterobacteriaceae strains isolated from 567 cultures were evaluated by a rapid kit method (Micro-ID; General Diagnostics, Morris Plains, N.J.; 4 h), an overnight incubation kit method (API 20E; Analytab Products, Plainview, N.Y.), and conventional biochemical test methodology (mostly overnight incubation and some rapid methods) to compare the amount of laboratory effort required...

The goal of this article is to make the PET/CT and SPECT/CT operator aware of common artifacts found in CT. In diagnostic imaging, the ability to render an accurate diagnosis requires the technologist to take steps to optimize image quality and recognize when image quality has been compromised-that is, when there is an image artifact. One way these artifacts occur is through the inability of th...

In Norway there is only one governemental regulating body, who register all health professionals in Norway. In Norway there is also only one legislative Act, which regulate all health professionals and there is one central database, with all registered health professionals in Norway. In Norway there are 29 regulated professions in the health care services, of which the medical laboratory techno...
