Discuss ways to develop an acceptable QC program for the analytical phase of testing. Negligence in any of these steps can lead to erroneous results attributed to preanalytical phase. Non-analytical automation within and outside the clinical laboratory will standardize as possible as the processes in that phase. Resultantly, the extra-analytical phase management may prevent some errors, resulting in the total quality of laboratory diagnostics and high-quality test results, as considered in the following sections. Year 2008]. Sonu olarak, laboratuvar tehislerinin toplam kalitesi ve daha yksek hasta gvenlii, bu tip otomasyonla yakndan baldr. Unfortunately, there are limited numbers of studies focusing on the error improvements by implemented tools. The management and standardization of non-analytical laboratory processes, especially of pre-analytical ones, have been primarily achieved thanks recently to automation, either by stand-alone devices or those integrated with analytical automation, as well as by informatics and computer sciences.

A patient should never be stuck more than twice unsuccessfully by a phlebotomist. What is the role of phlebotomist in pre analytical phase? While all members of the healthcare team play important roles in minimizing pre-analytical variability, those involved with direct patient contact and sample collection, primarily the phlebotomists, serve the most vital role in assuring sample quality and integrity, which leads to overall analytical accuracy. J Surg Oncol. Preanalytical variables occur prior to specimen testing and may include variables involving the process of obtaining a specimen. Extra-analytical and analytical components have recently been integrated or interfaced with each other to construct fully integrated modular laboratory automation. These non-analytical components of the testing pathway require improvement because of their potential to adversely affect patient care.
