Aggregated data from the same laboratories participating in two glucose external quality assessment schemes show that commutability and transfers of values to control materials are decisive for the biases found
(Journal article; Peer reviewed, 2023)Objectives We report the results of glucose measurements performed during one year by the same measurement procedures (MPs) in 58 Norwegian hospital laboratories using control materials provided by external quality ... -
Availability and analytical quality of hemoglobin A1c point-of-care testing in general practitioners’ offices are associated with better glycemic control in type 2 diabetes
(Journal article; Peer reviewed, 2020)Background: It is not clear if point-of-care (POC) testing for hemoglobin A1c (HbA1c) is associated with glycemic control in type 2 diabetes. Methods: In this cross-sectional study, we linked general practitioner (GP) ... -
Critical appraisal and meta-analysis of biological variation estimates for kidney related analytes
(Journal article; Peer reviewed, 2020)Objective: Kidney markers are some of the most frequently used laboratory tests in patient care, and correct clinical decision making depends upon knowledge and correct application of biological variation (BV) data. The ... -
The European Biological Variation Study (EuBIVAS): A summary report
(Journal article; Peer reviewed, 2022)Biological variation (BV) data have many important applications in laboratory medicine. Concerns about quality of published BV data led the European Federation of Clinical Chemistry and Laboratory Medicine (EFLM) 1st ... -
The European Biological Variation Study (EuBIVAS): weekly biological variation of cardiac troponin I estimated by the use of two different high-sensitivity cardiac troponin I assays
(Journal article; Peer reviewed, 2020)Background Cardiac troponins (cTn) are specific markers for cardiac damage and acute coronary syndromes. The availability of new high-sensitivity assays allows cTn detection in healthy people, thus permitting the estimation ... -
European Biological Variation Study (EuBIVAS): Within- and between-subject biological variation estimates for serum thyroid biomarkers based on weekly samplings from 91 healthy participants
(Journal article; Peer reviewed, 2022)Objectives: Thyroid biomarkers are fundamental for the diagnosis of thyroid disorders and for the monitoring and treatment of patients with these diseases. The knowledge of biological variation (BV) is important to define ... -
Evaluation of eleven rapid tests for detection of antibodies against SARS-CoV-2
(Journal article; Peer reviewed, 2020)Objectives: SARS-CoV-2, causing COVID-19, has emerged to cause a human pandemic. Detection of SARS-CoV-2 in respiratory samples by using PCR is the standard laboratory diagnostic tool. Our aim was to perform a limited ... -
External quality assessment of point-of-care International Normalized Ratio (INR) testing in Europe
(Peer reviewed; Journal article, 2011-09)Background: Point-of-care testing (POCT) of prothrombin time, expressed as International Normalized Ratio (INR), is widely used to monitor patients in oral anticoagulation treatment. Guidelines recommend that POCT users ... -
A national surveillance program for evaluating new reagent lots in medical laboratories
(Journal article; Peer reviewed, 2022)Objectives Differences between laboratory results attributable to the use of different reagent lots can potentially affect the diagnosis and monitoring of patients. To minimize patient risks, all laboratories should verify ... -
Performance of Afinion HbA1c measurements in general practice as judged by external quality assurance data
(Journal article; Peer reviewed, 2020)Background: It has been debated whether point-of care (POC) glycated hemoglobin (HbA1c) measurements methods can be used for diagnosing persons with diabetes mellitus. The aim of this study was to evaluate the analytical ... -
Personalized reference intervals - Statistical approaches and considerations
(Journal article; Peer reviewed, 2022)For many measurands, physicians depend on population-based reference intervals (popRI), when assessing laboratory test results. The availability of personalized reference intervals (prRI) may provide a means to improve the ... -
Point-of-care testing in primary healthcare: a scoring system to determine the frequency of performing internal quality control
(Journal article; Peer reviewed, 2022)Objectives Internal quality control (IQC) plays an important role in quality assurance in laboratory medicine. However, there is no universal consensus or guideline on when and how IQC should be analyzed on point-of-care ... -
Pre-analytical practices for routine coagulation tests in European laboratories. A collaborative study from the European Organisation for External Quality Assurance Providers in Laboratory Medicine (EQALM)
(Peer reviewed; Journal article, 2019)Background: Correct handling and storage of blood samples for coagulation tests are important to assure correct diagnosis and monitoring. The aim of this study was to assess the pre-analytical practices for routine coagulation ... -
Systematic review and meta-analysis of within-subject and between-subject biological variation estimates of 20 haematological parameters
(Peer reviewed; Journal article, 2020)Background: Interpretation of the complete blood count (CBC) parameters requires reliable biological variation (BV) data. The aims of this study were to appraise the quality of publications reporting BV data for CBC ... -
Within- and between-subject biological variation data for serum zinc, copper and selenium obtained from 68 apparently healthy Turkish subjects
(Journal article; Peer reviewed, 2022)Objectives: Trace elements (TrEL) are nutritionally essential components in maintaining health and preventing diseases. There is a lack of reliable biological variation (BV) data for TrELs, required for the diagnosis and ... -
Within- and between-subject biological variation data for tumor markers based on the European Biological Variation Study
(Journal article; Peer reviewed, 2022)Objectives: Reliable biological variation (BV) data are required for the clinical use of tumor markers in the diagnosis and monitoring of treatment effects in cancer. The European Biological Variation Study (EuBIVAS) was ...
