OBJECTIVES Pre-analytical error decisively influences the total error and consequently the diagnostic accuracy. The following were the objectives for the study: 1. To detect the percent of pre-analytical errors in clinical biochemistry laboratory. 2. To categorize these pre-analytical errors. 3. To formulate corrective measures to be taken to avoid such errors. DESIGN AND METHODS Study period...

development and optimisation of fast, efficient, quantitative, economic and environmentally friendly analytical extraction techniques for the extraction clean up, and pre-concentration in the quantification of 16 usepa priority polycyclic aromatic hydrocarbons (pahs) in contaminated soils have been carried out. three different extraction methods (soxhlet, ultra sonication and mechanical shaking...

Capillary electrophoresis (CE) poses unique challenges in many different analytical applications, mainly to biological and complex samples and when only small amounts of sample are available, due to its low sample consumption. As a consequence, poor limits of detection are usually observed with this technique, especially with UV photodetectors. Minimal or no sample treatment is desirable in any...

asimulation-optimization approach is proposed for replenishment planning andshelf space allocation. the customers’ demand is divided into fixed andvariable demand. each customer follows a given path while shopping in thestore. by dividing the store space into several zones and calculating therelated substantial and random utilities, an analytical equation is proposedfor the probability of zone ...

BACKGROUND Proficient laboratory service is the cornerstone of modern healthcare systems and has an impact on over 70% of medical decisions on admission, discharge, and medications. In recent years, there is an increasing awareness of the importance of errors in laboratory practice and their possible negative impact on patient outcomes. AIM We retrospectively analyzed data spanning a period o...
