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...
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: Measurement of cardiac troponins is of great importance in the diagnosis and follow-up of acute myocardial infarction. The diagnostic specificity of myocardial infarction has increased with algorithms including serial troponin measurements. It is important that the...
Objective: The cardiac troponins are sensitive and specific biochemical markers of myocardial damage. It has been suggested that hemolysis causes interference in the immunometric cardiac troponin assay. The current study aimed to determine the significance of hemolysis as an...
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...
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...
Purpose: A parameter associated with the result of a measurement that characterises the dispersion of the values that could reasonably be attributed to the measurand is defined as measurement uncertainty (U). Measurement uncertainty is very important for the clinician to...
Objective: The present study examines the effect of hemolysis on serum sodium concentrations in hyponatremic and hypernatremic serum samples.
Material and Methods: Samples were assessed by three different sodium methods; direct ISE by means of dry...
Aim: The aim of this study was to extensively evaluate four fully-automated photometric methods directly measuring antioxidant capacity; ferric ion reducing power, total antioxidant status, total antioxidant response, total thiol and to reveal the weak and strong sides of...
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...
Objectives: With the Department of Laboratory Services of the Ministry of Health entering into force with the general rule no. 2017/12, corrective actions were taken in the preanalytical, analytical and postanalytical processes related to the regulation of ethanol in the...
Objective: At Emergency Department, we aimed to compare the test results of serum samples obtained from the tubes containing thrombin to take short span of time for clotting (RST) with the tubes containing serum separator gel with clot activator (SST II Advance) that we have...
Purpose: It is critical to detect the errors in the preanalytical phases and reject the unsuitable samples for the patient safety and treatments. In this study, it is aimed to determine the situations where the samples reasons of rejectionare needed to be examined, developed...
Background: Cold agglutinin disease is a rare autoimmune hemolytic disease causing the agglutination of erythrocytes by the activation of antibodies at low temperatures. Cold agglutinin disease should be kept in mind in terms of getting the right diagnosis and treatment...
Purpose: A parameter associated with the result of a measurement that characterises the dispersion of the values that could reasonably be attributed to the measurand is defined as measurement uncertainty (U). Measurement uncertainty is very important for the clinician to...
Aim: In this study, it was aimed to evaluate the preanalytical process performance in our laboratory with the six-sigma methodology and to investigate the effect of the training given to the hospital staff on the sigma values.
Materials and Methods:...
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: Therapeutic drug monitoring for lithium therapy is important because of its narrow therapeutic range and non-specific nature of clinical findings of lithium toxicity. Methods such as ion-specific electrode (ISE), atomic absorption and flame emission have been used...
