In the last decades, a dramatic decr ease of analytical errors has been experienced, while a relatively high frequency of errors has been documented in the pr e-analytical phase. Most pr e-analytical errors, which account for up to 70% of all mistakes made in laborator y diagnostics, arise during patient pr eparation, and sample collection, transportation, preparation for analysis and storage. However , while it has been r eported that the pr e-analytical phase is error-prone, only r ecently has it been demonstrated that most of these errors occur in the »pre-pre-analytical phase«, which comprises the initial procedures of the testing process performed outside the laboratory walls by healthcare personnel outside the dir ect control of the clinical laborator y. Developments in automation and infor mation technologies have played a major r ole in decreasing some pre-analytical errors and, in particular, the automation of r epetitive, errorprone and bio-hazardous pre-analytical processes performed within the laboratory walls has effectively decreased errors in specimen preparation, centrifugation, aliquot pr eparation, pipetting and sorting. However, more efforts should be made to improve the appropriateness of test r equest, patient and sample identification pr ocedures and other pr e-analytical steps performed outside the laboratory walls.

متن کاملNumerical assessment of influence of confining stress on Kaiser effect using distinct element method
Nowadays acoustic emission (AE) testing based on the Kaiser Effect (KE) is increasingly used to estimate the in-situ stress in laboratories. In this work, this effect is assessed on cylindrical specimens in numerical simulations of the cyclic loadings including loading, unloading, and re-loading cycles using a 3D code called the particle flow code (PFC) based upon the distinct element method. T...

متن کاملEstimation of seed viability constants for tall wheatgrass, cocksfoot, rye, and sheep fescue to inform gene banking decisions. Hamid Reza Eisvand
Stored seeds deteriorate over time and must be regenerated to ensure that the benefits of ex situ conservation are realized. Prediction of seed longevity is based on the seed viability equation. This equation has four constants which are species specific. The aim of this project is the estimation of these constants and prediction of regeneration frequency for Elytrigia elongata, Dactylis glomer...
