The non-analytical automation, within and outside the clinical laboratory, will substantially lessen the effect of the error sources in TTP and enhance the quality of the test results, resulting in an accurate result(s) and faster test result reporting. The most commonly reported types of pre-analytical error are: a) missing sample and/or test request, b) wrong or missing identification, c) contamination from infusion route, d) haemolysed, clotted, and insufficient samples, e) inappropriate containers, f) inappropriate blood to anticoagulant ratio, and g) . Although the causes of these errors are largely com-mon to all laboratory medicine specialties, it is important for the haematology labora-tory to understand the particular impact of some on automated counting.

Accessibility Sources of Laboratory Error Traditionally, laboratory practice can be divided into 3 phases (pre-analytical, analytical, and post-analytical). Part 2: implementation of the system and performance measures over three years. government site. worse) than others. Consequently, laboratory professionals and staff cannot directly control and are not responsible for that phases errors. A questionnaire was distributed to 298 hospital laboratories whom participated in the External Quality Assessment Scheme in Clinical Chemistry (EQAC) program of Faculty of Medical Technology, Mahidol University. Decapper, aliquoter, bar-code labeler, recapper units of modular pre-analytical prevent these errors. Under these main categories, Lippi et al. 1. Non-analytical automated systems should be implemented in the laboratory processes. Fortunately, those kinds of errors have been able to be prevented partly by the introduction of some technological and computer-aided informatic solutions to that phase.
