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...
objective(s) a sensitive liquid chromatographic method for the analysis of clarithromycin- a macrolide antibiotic- in human serum, using pre-column derivatization with 9-fluorenylmethyl chloroformate (fmoc-cl) is described. materials and methods the method involved liquid-liquid extraction of the drug and an internal standard (amantadine) followed by pre-column derivatization of the analytes wi...
analytical solutions and type curves for the constant rate radial flow of fluid in both conventional and naturally fractured reservoirs including the effect of wellbore phase redistribution are presented. an automated procedure for non-linear least square minimization using the analytical solutions and their derivatives with respect to the unknown parameters developed to analyze the pressure bu...
the quality of pre-hospital oxygen therapy in patients with multiple trauma: a cross-sectional study
background: trauma is a major healthcare challenge worldwide. in developing countries, most road deaths happen during the pre-hospital phase; consequently, pre-hospital trauma care has received considerable attention during the past decades. objectives: the aim of this study was to investigate the quality of pre-hospital oxygen therapy in patients with multiple trauma. patients and methods: thi...
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...
Are the current Covid-19 cases post phase of 3rd wave or pre-phase of 4th wave in India?
BACKGROUND Various publications have highlighted the significance of laboratory errors in the pre- and post-analytical phases and their impact on results. Thyroid-stimulating hormone (TSH) is a first-line thyroid function test and, if abnormal, reflex thyroxine (T4) or tri-iodothyronine (T3) testing is requested, depending on clinical and medication data provided. Interpretative comments are ad...
ABSTRACT Fluoroquinolones of the third and fourth generation posses wide bactericidal activity. Monitoring concentrations of antibacterial agents provides effective therapy and prevents the increase of bacterial resistance to antibiotics. The pharmacodynamic parameters that best describe fluoroquinalone activity are AUC/MIC and Cmax/MIC. Determining the level of this type of drug is essential t...
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...
