Evaluation of quality indicators in the hematology laboratory of Al-Azhar University Hospitals (Assiut Branch): a cross-sectional study

Al-Azhar Assiut Medical Journal
Background and aim Laboratory errors can compromise patient safety. Quality indicators (QIs) are essential tools for monitoring and improving laboratory performance, particularly in the error-prone preanalytical phase. We aimed to evaluate QIs across the

The Role of Nitrous Oxide (“Laughing Gas”) in DUID Cases and Its Impact on Driving Fitness

Drug Testing and Analysis, EarlyView.
A total number of 39 cases of driving under the influence of nitrous oxide were investigated. Plasma concentrations of 0.22 to 17 mL/L (median:3.7 mL/L) were measured in blood samples withdrawn 38 to 144 min (median: 85 min) after control via Headspace‐GC–MS.

Improving wound swab collection in paediatric patients: a quality improvement project

BMJ Open Quality, 2023
Microbiology sample swabs may be unsuccessful or rejected for a variety of reasons. Typically, errors occur in the preanalytical phase of sample collection. Errors with collection, handling and transport can lead to the need to repeat specimen collection.

Quality Assurance in the Preanalytical Phase

, 2011
The preanalytical phase includes a set of processes that are difficult to define because they take place in different places and at different times. Classically, the preanalytical phase included all processes from the time a laboratory request is made by a physician until the sample is ready for testing.

Pretreatment EBV‐DNA/TLG‐Based Risk Stratification Is Associated With Survival Outcomes in Nonmetastatic Nasopharyngeal Carcinoma: An Exploratory Study

International Journal of Cancer, EarlyView.
ABSTRACT Whether combining pretreatment plasma Epstein–Barr virus DNA (EBV‐DNA) with 18F‐FDG PET/CT‐derived total lesion glycolysis (TLG) improves prognostic stratification in nonmetastatic nasopharyngeal carcinoma (NPC) is unclear, particularly in nonendemic populations.

Quality Indicators in the Preanalytical Phase of Testing in a Stat Laboratory [PDF]

Laboratory Medicine, 2014
To quantify performance in the preanalytical phase in a stat laboratory using quality indicators, and compare our results with those in the literature to improve laboratory services.We counted the test request forms, samples, and the types of preanalytical errors that occured in a stat laboratory between January 1 and December 31, 2011.

MicroRNA‐210 level as a biomarker for pre‐eclampsia severity: A systematic review and meta‐analysis

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Background Pre‐eclampsia is a serious pregnancy‐related syndrome lacking accurate prognostic markers. MicroRNA‐210, overexpressed in the circulation of women with pre‐eclampsia, has recently emerged as a promising biomarker. Objectives We conducted a systematic review and meta‐analysis to evaluate the relationship between miR‐210 levels and ...

Improving the preanalytical process: the focus on specimen quality [PDF]

Journal of Medical Biochemistry, 2008
Trends in clinical laboratory practice place more demands on the quality of patient specimens. Advances in analytical performance (i.e., increased automation, reduced sample volume, increased assay sensitivity), as well as efficiency and cost reduction ...

Establishment and Application of a Quantitative Lipemia Index as a Novel Indicator for Assessing Lipemic Interference in Clinical Chemistry

Journal of Clinical Laboratory Analysis, EarlyView.
A rigorously validated quantitative lipemia index (LI) assay was established for direct serum turbidity measurement. This standardized LI metric demonstrated significantly stronger correlation with lipemic interference (rs = 0.822) than conventional triglyceride concentration (rs = 0.770), consistent with its direct measurement of optical turbidity ...

Mass Spectrometry Insights Into Post‐Translational Modifications in Extracellular Vesicles

Mass Spectrometry Reviews, EarlyView.
ABSTRACT Extracellular vesicles (EVs) are membrane‐enclosed structures secreted by virtually all living cells, serving as essential mediators of intercellular communication in both physiological and pathological processes. There is growing interest in their potential applications as biomarkers, therapeutic targets, and drug delivery systems, which ...
