Article Synopsis
- * Results indicated that certain tests, particularly cardiac biomarkers, blood gases, and specific drug levels, were perceived to pose a higher risk for patient harm due to erroneous results.
- * There was strong agreement (91%) between medical biochemists and clinicians regarding the severity scores, highlighting the tests that require focused quality improvement efforts.
Aim: Measuring uncertainty (MU) is crucial to ensure the accuracy and precision of laboratory results. This study compares the ISO 20914 and Nordtest guidelines to analyze the MU values for 20 clinical chemistry analytes over six months.
Methods: The researchers calculated MU components, including within-laboratory reproducibility (Rw), laboratory analytical performance bias ((bias)), and combined standard uncertainty (), based on internal quality control and external quality assessment data.
A comparative analysis of Sigma metrics using conventional and alternative formulas.

Background And Aim: The Six Sigma approach, employing Sigma Metrics (SM), is commonly used to evaluate analytical performance in clinical laboratories. However, there is ongoing debate regarding the suitability of the conventional SM formula, which incorporates total allowable error (TEa) and bias. To address this, an alternative formula based on within-subject biological variation (CV) as the tolerance range (TR) has been proposed.

Methods: Forty volunteers were included in the study. Blood samples were collected using two different modes in the S-Monovette citrate tube (Sarstedt AG).
Background: We aimed to compare the Sarstedt S-Monovette serum gel tube and the BD (Becton, Dickinson and Company) Serum Separator Tube II (SST II) Advance based on technical specifications and tests results.
Methods: One hundred and twenty volunteers were included in the technical evaluation and 42 of 120 volunteers in the clinical evaluation. Blood was collected into S-Monovette, and SST II.
Background: The European Federation of Clinical Chemistry and Laboratory Medicine (EFLM) Working Group for Preanalytical Phase (WG-PRE) have recommended an algorithm based on the reference change value (RCV) to evaluate hemolysis. We utilized this algorithm to analyze hemolysis-sensitive parameters.
Methods: Two tubes of blood were collected from each of the 10 participants, one of which was subjected to mechanical trauma while the other was centrifuged directly.
Introduction: We investigated the interference of haemolysis on ethanol testing carried out with the Synchron assay kit using an AU680 autoanalyser (Beckman Coulter, Brea, USA).
Materials And Methods: Two tubes of plasma samples were collected from 20 volunteers. Mechanical haemolysis was performed in one tube, and no other intervention was performed in the other tube.
