Frequent, preventable medical errors can have an adverse effect on patient safety and quality as well as leading to wasted resources. In the laboratory, errors can occur at any stage of sample processing; pre-analytical, analytical, and post analytical stages. However evidence shows most of the laboratory errors occur during the pre-analytical stage. The receipt and processing of specimens is o...
Harmonization in laboratory testing is more far-reaching than merely analytical harmonization. It includes all aspects of the total testing process from the "pre-pre-analytical" phase through analysis to the "post-post-analytical" phase. Harmonizing the pre-analytical phase requires use of standardized operating procedures for correct test selection, sample collection and handling, while standa...
clinical laboratory results play an important role in helping physicians in diagnosis and treatment. in view of the direct effect of the working methods on the quality of data in the laboratory, quality control of data and results in the biochemistry ward of laboratory includes taking into account all the factors and variables relating to all the pre-analytical, analytical and post-analytical s...
Tau proteins and amyloid-β (Aβ) peptides are the current recognized cerebrospinal fluid (CSF) biomarkers used as an aid in the diagnosis of Alzheimer's disease (AD). However, there is no consensus on their clinical use due to non-qualified cut-off values, probably related to the observed high pre-analytical and analytical variability. Standardized pre-analytical protocols have therefore been pr...
Analysis of penetration in pre-drilled and damaged concrete targets is the main part of anti-structure tandem warhead researches. In this paper the penetration process of the KE projectiles is investigated in pre-drilled and damaged concrete targets by analytical and numerical method. In this research, it has been tried to modify the teland model for achieving an accurate and efficient analytic...
