Aim: The aim of this study was to calculate the uncertainty of the hs-cTn I test in which the clinical decision limit value was important and to evaluate the possible effect of the calculated measurement uncertainty for the test result interpretation at the clinical decision...
Aim: Measurement uncertainty provides information about the limits at which the measured value may vary as a result of random effects in a biochemical measurement. It is a quantitative indicator of the quality of the result obtained and allows us to estimate the extent to...
Aim: /b> In this study, we evaluated the analytical performance and diagnostic adequacy of the activity and mass methods used for the measurement of CK-MB, a laboratory marker for the diagnosis of acute myocardial infarction (AMI). In addition, the differences between CK-MB...
Objective: This study aimed to evaluate the agreement between albumin measurements obtained via capillary zone electrophoresis (CZE) and bromocresol green (BCG) methods and to determine their interchangeability in clinical practice. Additionally, it explored how these results...
Objective: Immune methods those were used in the laboratories for serum TSH measurements, were standardized. Functional sensitivity of TSH tests is expected to be ²0.02 mIU/L. We aimed to compare the performances of three different immunassay devices for third generation TSH...
Purpose: The measurement uncertainty is a quantitative indicator of the quality of the test result obtained and indicates how the test results represent the actual value. For this reason, we aimed to calculate the measurement uncertainty for the 25-hydroxyvitamin D3 assay,...
Objective: This study aimed to evaluate the frequency of repeat lipoprotein(a) testing, determine whether repeated measurements changed risk classification, assess the clinical significance of observed changes using the reference change value, and investigate whether the...
Objective: Measurement uncertainty is a useful method to obtain objective information about laboratory performance, to identify analytes that need analytical improvement in clinical use, and to abandon analytes of inadequate quality. The aim of the study was to calculate the...
