Pre and Post Analytical Factors Affecting Laboratory Results

Ethylene glycol poisoning: toxicokinetic and analytical factors affecting laboratory diagnosis.

Ethylene glycol poisoning is an important toxicological problem in medical practice because early diagnosis and treatment can prevent considerable morbidity and mortality. When ingested in the form of antifreeze or other automotive products, ethylene glycol results in central nervous system depression, cardiopulmonary compromise, and renal insufficiency. Metabolism of ethylene glycol to organic...

Improving Laboratory Results Turnaround Time By Reducing Pre Analytical Phase

Laboratory turnaround time is considered one of the most important indicators of work efficiency in hospitals, physicians always need timely results to take effective clinical decisions especially in the emergency department where these results can guide physicians whether to admit patients to the hospital, discharge them home or do further investigations. A retrospective data analysis study wa...

Factors affecting laboratory test use and prices

The use of clinical laboratory tests has more than doubled during the past decade. Some observers of the health system feel that this growth is excessive and is a result of current payment systems. This article examines the effects of current reimbursement policies with regard to the use of laboratory tests and prices charged for tests. The results suggest the following: The method of financing...

Critical care analytes: pre-analytical factors affecting result quality for combined blood gas and electrolyte systems

Factors affecting pre- and post-stenting computed tomography perfusion in patients with middle cerebral artery stenosis

The aim of this study was to investigate the factors affecting pre- and post-stenting head computed tomography perfusion (CTP) in patients with middle cerebral artery stenosis. A total of 25 patients with severe middle cerebral artery stenosis were enrolled. CTP was performed prior to and following stenting. Scores were allocated to the time-to-peak (TTP) parameter of CTP using the Alberta stro...
