Pre-analytical errors in clinical laboratory Role of a. The identification of reliable quality indicators (QIs) is a crucial step in enabling users to quantify the quality of laboratory services. The current lack of attention to extra-laboratory factors is in stark contrast to the body of evidence pointing to the multitude of errors that continue to occur, particularly in the pre-analytical phase., with increased laboratory quality (mainly analytical), the literature on errors in laboratory medicine is scarce. One reason for this, in addition to the insufficient attention paid to the problem, is the practical difficulty in reporting and measuring the number of errors. ….

Laboratory errors might occur at any of these three phases, depending upon their source and time of presentation respectively. The pre-and post-analytical phases of the process account for 93% of the errors [3].

The source of this commonly accepted knowledge about laboratory errors is an abstract, not a peer-reviewed paper [see the complete abstract in an earlier discussion on this website]. It seems that people want to believe that analytical errors aren't as frequent as the pre-analytical and post-analytical errors. Preanalytical errors are quite frequent in the area of point-of-care testing (POCT). There are many reasons for that. First of all, POCT testing is usually performed by clinical staff (i.e. nurses and physicians), who are neither so skilled nor educated for laboratory work as laboratory professionals.

In recent years, there is an increasing awareness of the importance of errors in laboratory practice and their possible negative impact on patient outcomes. We retrospectively analyzed data spanning a period of 3 years on analytical errors observed in our laboratory. 1/3/2019 · Background: We compared the rates of intraoperative parathyroid hormone (PTH) decline using the Siemens Immulite® Turbo PTH and Roche Elecsys® short turnaround time PTH assays in 95 consecutive surgical patients to investigate analytical and turnaround time (TAT) differences between the tests performed in the operating room (OR) vs the
