Background: Laboratory turnaround time is considered one of the most important indicators work efficiency in hospitals, physicians always need timely results to take effective clinical decisions especially emergency department where these can guide whether admit patients hospital, discharge them home or do further investigations. Objectives:1. Calculate for various biochemical investigations fr...
An automated solid phase extraction (SPE) protocol to determine carbamazepine in human serum has been developed and validated using a simple, rabid sensitive liquid chromatography-based bio-analytical method. Extraction of was carried out an on-line SPE tool short protein-coated (PC) ODS silica pre-column (PC-ODS-pre-column) phosphate buffer saline (PBS) with pH 7.4 as solvent. There are two di...
Intraplatelet phospho-VASP analysis is a commonly used approach for monitoring of anti-platelet therapy; however, testing of intraplatelet phospho-VASP expression needs a high level of experience and proficiency. The ability to recognize how the pre-analytical variations can change the results would be helpful for the interpretation of data from intraplatelet P-VASP analysis. The aim of this st...
Clinical biochemistry has long been utilized in human and veterinary medicine as a vital diagnostic tool, but despite occasional studies showing its usefulness in monitoring health status in Atlantic salmon (Salmo salar L.), it has not yet been widely utilized within the aquaculture industry. This is due, in part, to a lack of an agreed protocol for collection and processing of blood prior to a...
Over the past three decades, the goal of many researchers is analysis of exhaled breath condensate (EBC) as noninvasively obtained sample. A total quality in laboratory diagnostic processes in EBC analysis was investigated: pre-analytical (formation, collection, storage of EBC), analytical (sensitivity of applied methods, standardization) and post-analytical (interpretation of results) phases. ...
We present the design, fabrication and testing of the piece-wise stepped-chirp fiber Bragg gratings (FBGs) with arbitrary group delay responses using a uniform phase mask under pre-stretched condition. The method involves writing a series of sub-gratings on a prestretched fiber whose length is varied during the UV exposure process. Two motorized stages are employed to control the length of the ...
The EC4 Syllabus for Postgraduate Training is the basis for the European Register of Specialists in Clinical Chemistry and Laboratory Medicine. The syllabus: Indicates the level of requirements in postgraduate training to harmonise the postgraduate education in the European Union (EU); Indicates the level of content of national training programmes to obtain adequate knowledge and experience; Is...
Technical progress has simplified tasks in lab diagnosis and improved quality of test results. Errors occurring during the pre-analytical phase have more negative impact on the quality of test results than errors encountered during the total analytical process. Different infrastructures of sampling sites can highly influence the quality of samples and therewith of analytical results. Annually t...
Management of pre analytical nonconformities within a laboratory is critical step in ensuring the reliability results. The objectives this study are to evaluate non-compliance pre-analytical phase at Paraclinical Training and Biochemistry Research Unit Joseph Ravoahangy Andrianavalona University Hospital Center, describe detail state play progress stage. This retrospective descriptive over peri...
We have determined routinely administered benzodiazepines and some of their metabolites in clinical samples by using on-line column switching for sample clean-up and reversed-phase high-pressure liquid chromatography (HPLC). The plasma sample is directly injected onto a cyanopropyl (CN) pre-column, washed with buffer, and eluted onto an analytical column (C18, octadecylsilane). Analytical recov...
