Objective: Autoimmunity is an important factor in the pathogenesis of Behcet Disease emphasized in recent years In recent studies, Vitamin D has been demonstrated to play a significant role in immune system functioning. The measurement of plasma 25-hydroxyvitamin D3levels,...
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,...
Aim: Reference intervals/ranges are the most widely used decision-making tool in laboratory medicine and serve as the basis for many of the interpretations of test results. There is no agreement on the reference (normal) ranges for serum total 25-hydroxyvitamin D (25(OH)D)...
