background and objective: the reliability and validity of monitors for self-monitoring of blood glucose are debated. we evaluated the analytical performance of accu-check active (boehringer mannheim, roche) which is one of the most commonly used monitors in iran. material and methods: we compared the monitor readings with the reference values by percentage of values within certain intervals of...

OBJECTIVES Pre-analytical error decisively influences the total error and consequently the diagnostic accuracy. The following were the objectives for the study: 1. To detect the percent of pre-analytical errors in clinical biochemistry laboratory. 2. To categorize these pre-analytical errors. 3. To formulate corrective measures to be taken to avoid such errors. DESIGN AND METHODS Study period...

Numerous outcome measures can be used to characterize and compare the performance of alternative quality-control (QC) strategies. The performance measure traditionally used in the QC planning process is the probability of rejecting an analytical run when a critical out-of-control error condition exists. Another performance measure that naturally fits within the total allowable error paradigm is...

Glucose performance is reviewed in the context of total error, which includes error from all sources, not just analytical. Many standards require less than 100% of results to be within specific tolerance limits. Analytical error represents the difference between tested glucose and reference method glucose. Medical errors include analytical errors whose magnitude is great enough to likely result...

Karon et al. (1 ) modeled the effects of glucose meter error on insulin dosing errors. They refer to an earlier model that I had pointed out was incomplete (2 ). Although Boyd and Bruns (3 ) agreed with my assessment, the current simulation is, once again, incomplete and the same as the previous simulation. We have reviewed the statistics for glucose meter performance (4 ) and noted that Lawton...

BACKGROUND It is important for a laboratory to know the stability of performance of laboratory tests over time. The aim of this study was to adapt from the field of clinical chemistry a method to assess the long-term analytical performance of hemostasis field methods. METHODS The linear regression model was used to compare the laboratory results with the consensus mean value of a survey. This...

BACKGROUND Proficient laboratory service is the cornerstone of modern healthcare systems and has an impact on over 70% of medical decisions on admission, discharge, and medications. In recent years, there is an increasing awareness of the importance of errors in laboratory practice and their possible negative impact on patient outcomes. AIM We retrospectively analyzed data spanning a period o...
