"Evaluation & Control of Pre Analytical Errors in Required Quality Variables of Clinical Lab Services -"

Since the beginning of modern clinical labs in 1950s in West and early 1970s in Pakistan, quality assurances (QA) become the prime area of concern as well as of utmost priority. Regarding QA, the most important criterion or the category that the labs always cater to manage and evaluate most often are "Errors" in lab services, which is divided into three parts, Pre-analytical, analytical and post-analytical. These are the commonly accepted criteria's regarding lab working and services and thus regarded as back-bone of any management of Lab. Proper laboratory management system, whether part of the pre-analytical hierarchy, analytical labs or post-analytical arrangements, always keeps evaluating the categories, through continual assessments, working, estimating the possibilities and supervising the lab components, to avoid errors in labs and proving quality assured services to its patients.
