Objective: The laboratory critical values are the laboratory testing results which required attention or action by the physicians. The aim of this study is to investigate the laboratory critical value notification process in our laboratory in terms of patient safety and...

Purpose: Hemolysis is one of the most important preanalytical factors affecting the laboratory test results. It is mostly seen in blood samples sent from the emergency department compared to all samples accepted to the laboratory. If hemolysis is present, the tests affected...

Aim: The Intra-laboratory Turnaround Time (IR-TAT) serves as a significant measure of overall laboratory efficacy. This study sought to augment laboratory operational productivity and diminish IR-TAT by instating a Total Laboratory Automation (TLA) system, executing stat...

Aim: Hemolyzed specimens are often a significant cause of economic and clinical problems between the clinics and the laboratory. The rate of hemolysis is markedly higher in the Emergency Department (ED) as compared with other hospital departments. We aimed to reduce the rate...

Objective: To determine the preanalytical errors in specimens sent from the emergency department to the laboratory and to evaluate the causes and the consequences.

Material and Methods: All the specimens sent from the emergency department were...

Objective: In the clinical laboratories, the same test could be analyzed by more than one assay system or analyzer due to various requirements. This may cause a problem in patient monitoring. In our laboratory, stat TSH testing has been recently implemented in the stat...

Objective: Use of C-Reactive protein in the follow-up of different clinical situations is getting more important. Levels of CRP can be detected by immunonephelometric and immunoturbidimetric methods in the clinical laboratories. The emergency departmentÕs laboratory renders...

Aim: The aim of the study was to evaluate the sample rejections reasons by the quality indicators and six sigma process, to determine the acceptability of the rejection reasons and to improve them during the follow-up process.

Material and Method: The...

Objectives: This study aims to analyze the turnaround time (TAT) of intraoperative PTH (parathyroid hormone) testing and to support surgical success with objective criteria by calculating reference change values (RCV).

Methods: TAT analysis was...

Purpose: Rejection of unsuitable samples is important for the quality of the laboratory results. In our study, it is aimed to perform sample rejection analysis of blood samples from outpatient, inpatient and emergency units and to evaluate the effectiveness of the training...

Objective: It has been predicted that 60-70 % of critical decisions are based on laboratory results. Sodium is one of the most frequently tested analytes in the clinical laboratory. Hyponatremia is common inconvenience of sodium metabolism in hospital patients, with a...

In this article, an evaluation about drug abuse testing in the clinical laboratories was done. Ministry of Health has made arrangements for drug abuse testing in laboratory-related services; according to final tasks from Rule of Medical Laboratories and the National Emergency Action Plan...

Objective: Although there have been many studies about the pre-analytic errors of hemolysis on laboratory tests, different results were found with different work environments and different methods. This study was put together to investigate the effects of hemolysis on routine...

Objective: C-reactive protein (CRP) is one of acute phase respondents that has been used to monitor infection and inflammation episodes. In our hospitals' emergency laboratory, CRP analysis is done with a point of care testing device (i-chroma). In our central biochemistry...

Objective: If a new analyzer in the laboratories is considered to be used, method comparison should be done. Two analyzers should be compared in order to evaluate accuracy of the new analyzer. In our study, we aimed to compare the performance of new coagulation analyzer with...

Objective: Troponin I is a reliable and sensitive marker which is used to evaluate the myocardial injury. However there are different cut-off values for Troponin I due to different measurement technics. Therefore it is recommended that laboratories must define their own...

Objective: Preanalytical variables account for most of laboratory errors and there are many factors that affect and contribute to the results from a patient. In recent years surgeons use intraoperative parathormone (PTH) results to evaluate the efficiency of...

Objective: The objective of this study was to evaluate of accuracy of the immuno-turbidimetric method.

Material and Methods: Patients (n=160) were tested with the D-Dimer assay with a STalia®D-DI (D-dimer) (Diagnostica Stago, Asnieres, France). D-dimer...
